Answer:
To graph the equation, you need to find the slope and y-intercept.
y = mx + b
⬑[slope-intercept formula; m is the slope, and b is the y-intercept]
y = 4x + −1
⬑[given equation before being simplified]
y = 4x − 1
⬑[given equation]
║m = 4
║b = (0, −1)
Proof:
m = [tex]\frac{rise}{run}[/tex] = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
x₁ = 0
x₂ = 1
y₁ = −1
y₂ = 3
m = [tex]\frac{3 - -1}{1 - 0}[/tex]
║m = 4
║b = (0, −1)
[the value for x₁ and y₁ equals the y-intercept: (0, −1)]

Find an equation of the line containing the points (1,4) and (3,18).
Answer:
y=7x-3
Step-by-step explanation:
(1,4). y=mx+b or 4=7 × 1+b, or solving for b: b=4-(7)(1). b=-3.
(3,18). y=mx+b or 18=7 × 3+b, or solving for b: b=18-(7)(3). b=-3.
hence, y=7x-3
This is the slope intercept form for the points, not sure if you wanted it in standard form or point slope form...
Answer:
y = 7x
Step-by-step explanation:
[tex]\frac{18-4}{3-1}[/tex] = [tex]\frac{14}{2}[/tex] = 7
y = 7x

About 35% of all U.S. households have a cellular phone. If you called 7 households what's the probability that, a. All 7 households have a cellular phone? a= b. Exactly 4 households have a cellular phone? b = c. Fewer than 2 households have a cell phone? c = d. At least 6 households have a cellular phone? d = e. At least 1 household has a cellular phone? e =
Answer:
p = 0.35
q = 0.65
n = 7
Step-by-step explanation:
To calculate the distribution, we have the following values;
p = 35% = 35/100 = 0.35
q = 1-p = 1-0.35 = 0.65
n = 7

Select the equation of the line parallel to y= -3x -5 the equation and that passes through the point (1,2)
Answer:
[tex]y=-3x+5[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (b)Parallel lines always have the slope slopes and different y-intercepts1) Determine the slope (m)
[tex]y= -3x -5[/tex]
With the given line, we can identify clearly that -3 is in the place of m, making it the slope. Because parallel lines have the same slopes, the slope of the line we're currently solving for would also be -3. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-3x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=-3x+b[/tex]
Plug in the given point (1,2) and isolate b
[tex]2=-3(1)+b\\2=-3+b[/tex]
Add 3 to both sides
[tex]2+3=-3+b+3\\5=b[/tex]
Therefore, the y-intercept of the line is 5. Plug this back into [tex]y=-3x+b[/tex]:
[tex]y=-3x+5[/tex]
I hope this helps!

Which rule can be used to find the output numbers in this table?
Answer:
D
Step-by-step explanation:
22/11 = 2
77/11 = 7
110 /11 = 10
121/11 = 11
In each case, when you divide the input by 11 you get the output.
The rule is to divide the input by 11.

How do we define transformation?
Answer:
A Dramatic change in appearance or form
Step-by-step explanation:
Answer:
A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system. Mathematical transformations describe how two-dimensional figures move around a plane or coordinate system. A preimage or inverse image is the two-dimensional shape before any transformation.

Hi guys I need your help here I'll give 100 points and also brainiest no link's please I need this by today thank you : )
Answer:
#2CD ║ EF and ED is transversal, hence
∠CDE ≅ ∠FED ⇒ m∠CDE = m∠FED ⇒ m∠CDE = 28° as alternate interior anglesm∠CDB = 160° - 28° = 132°We can see that:
m∠CDB + m∠ABD = 132° + 48° = 180°Since the angles CDB and ADB sum to 180, these are consecutive interior angles, therefore AB and CD are parallel lines.
#3PU and QT are parallel and PT is transversal, therefore:
∠UPT ≅ ∠QTP as alternate interior anglesm∠UPT = m∠QTP = 42° or x = 42°Now find the missing angles of ΔQTP
x + 40° = 42° + 40° = 82°y = 180° - (42° + 82°) = 56°Now, we see that:
m∠TPQ = 82°m∠SQR = 82°As ∠TPQ ≅ ∠SQR these angles are corresponding angles.
Therefore PT and SQ are parallel lines.
