Question

What would be the best first step to convert 5x-y=7 to slope intercept form?

Question 1 options:

Multiply both sides by -1


-5x from both sides


+5x to both sides


Subtract 7 from both sides

Answer 1

Subtract 5x from both sides

Answer 2

-5x from both sides

Explanation:

When converting an equation to slope-intercept form, you need to isolate the y. The first step in isolating the y is to remove 5x from both sides of the equation:

5x - y = 7

5x - 5x - y = 7 - 5x

-y = 7 - 5x

Now it's just -1y on one side of the equation.
