Question

How do i do this pls help me

standard form (ax + by = c) to slope-intercept form (y = mx + b)

5x+7y= -21 (ANSWER?)

Answer 1

y=-5/7x-3

Explanation:

so, we need the equation to be in y=mx+b form.

The equation right now is 5x+7y=-21 in standard form.

We need to isolate y onto one side

Here's the equation:

5x+7y=-21

subtract 5x from both sides

7y=-5x-21

divide by 7

y=-5/7x-21/7

simplify

y=-5/7x-3

Hope this helps! :)
