Slope-intercept form:

y = mx + b ["m" is the slope, "b" is the y-intercept (the y value when x = 0)]

So all you need to do is get "y" by itself:

9x - 7y = -7 Subtract 9x on both sides

9x - 9x - 7y = -7 - 9x

-7y = -7 - 9x Divide -7 on both sides

(-7y)/(-7)=(-7-9x)/(-7)

y =1+ (9)/(7)x or
y=(9)/(7)x+1 (I just rearranged it)
