Question

Does this look correct?

Write the equation 9x+2y=6 in slope-intercept form.
2. 9x+2y=6
9x-9x+2y=6-9
x+2y=-3
x+2y/2=-3/2
x+y=-1.5

Answer 1

That is not correct. I will help you. Begin by subtracting the 9x from both sides, like this: 9x - 9x + 2y = 6 - 9x. That simplifies to 2y = -9x + 6. Now divide both sides by 2 to get y all alone, like this:
`(2y)/(2)=- (9)/(2)x+ (6)/(2)`. That reduces down to
`y=- (9)/(2)x+3`. That is slope-intercept form. y = mx + b.
