Question

Find the slope and the y-intercept of the line.
7x=9y+81

Answer 1

re-write it as:
9y=7x-81
y=7/9 x -9
the slope is the coefficient in a front of x..
what is slope equal to?

Answer 2

y-intercept => x=0
if x=0 what is y=?

Answer 3

the slope is 7/9 the y intercept is (-9,0). you need to change it to y=mx+b (slope-intercept form) m is the slope and b is your y intercept.

Answer 4

slope m=7/9
y-intercept: y=-9 or like Jerni wrote: (0,-9)

got to go , guys...good luck!

Answer 5

Thanks
