Answer 2

you can use slope-intercept form

Answer 3

how?

Answer 4

can you determine the value of slope?

Answer 5

no

Answer 6

i'm sorry, you're going to use the point-slope form
which is ; y-y1=m(x-x1)

Answer 7

where m is the slope

Answer 8

@lilyflower19 since the line is vertical the slope if zero, if it's horizontal it's infinity.. then just substitute to the equation of point-slope form,, and poof! you got your equation of the line

Answer 9

thank you :-)
