Answer 1

do you know the slope-intercept equation?

Answer 2

can you plot the point (-9, 3)?
can you identify the line x= 9?
what do you know about perpendicular lines?

Answer 3

It is y=mx+b I know how to plot the point and line =x9 is a point resting on 0,9. Don't know much about perpendicular lines.

Answer 4

ok. but x = 9 means no change is x value slope change in y over 0
for perpendicular lines the product of their slopes is -1
