Question

Change 2x + 5y = –30 to slope-intercept form and state the slope and y-intercept?

Answer 1

slope intercept from is y=mx+b

so, 2x + 5y = -30

minus 2x from both sides

now you have

5y = -2x - 30

now to get y alone you divide everything by 5

y = -2x-30/5

you can simplify to

y = -2/5x - 6

so slope is -2/5 and y int = (0,-6)

Answer 2

y = (-2/5)X-6
the slope is -2/5
the y intercept is -6

Thank you:)
