What is 4x-2y=8 in slope intercept form?

Answers

Answer: y = -2x + 4

Step-by-step explanation: In slope-intercept form or y = mx + b form,

the y is isolated or by itself on the left side of the equation.

So start by subtracting 4x from both sides.

That gives us -2y = 4x - 8.

Notice I put the x term first because in y = mx + b form,

the x term comes first on the left side of the equation.

From here, we divide both sides by -2 to get y = -2x + 4.

Slope form is y=mx+b
Y=2x-4
m=2, b= -4

2/4=x/12 is the proportion can be used to calculate how many cups of salt Taryn needs to make 12 cups of playdough.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that Taryn used 2 cups of salt to make 4 cups of homemade playdough.

We need to find the proportion can be used to calculate how many cups of salt Taryn needs to make 12 cups of playdough.

Let x be the number of cups if salt to make 12 cups of playdough.

2/4=x/12

Apply cross multiplication

24=4x

Divide both sides by 4

x=6

Hence, 2/4=x/12 is the proportion can be used to calculate how many cups of salt Taryn needs to make 12 cups of playdough.

The dependent variable, which will go on the y-axis, is the

Answers

Answer:

The independent variable on the x-axis is the price of a t-shirt and the dependent variable on the y-axis is the number of t-shirts sold.

Step-by-step explanation:

To understand this question, it is crucial to understand what independent and dependent variables are. The independent variable is the one that is manipulated in an experiment. On the other hand, the dependent variable is the one that changes because of a change in the independent variable.

In this problem, the independent variable is the price of a t-shirt. Sera is able to change the price of her t-shirts at will, and changing it will impact the number of t-shirts sold. So, the dependent variable is the number of shirts sold. Sera has no direct control over this variable. She hopes that she will be able to control it by changing the cost of the t-shirts she sells.

Therefore, the independent variable is the price of a t-shirt and the dependent variable is the number of t-shirts sold.
