Question

Determine the equation of the line that passes through the points (2, -5) and (7, 0). Use the form y = mx + b.

Answer 1

Find the slope first, using

\[\huge m = \frac{ y_{2}-y _{1} }{ x _{2}-x _{1} }\]

Once you have that use the point - slope form.

\[\huge y-y _{1}=m(x-x _{1})\]

Form that into y = mx+b

Answer 2

m = slope
(x1,y1) your first point.

Answer 3

y = 2x - 5 ?

Answer 4

y = x + 7 ???

Answer 5

You sure it's +7?

Answer 6

A. y = 2x - 5 B. y = x + 7
C. y = 5x + 5 D. y = x - 7

Answer 7

y=x-7

Answer 8

Correct ?
