equation of the line that passes through the points

Question

Write the equation of the line that passes through the points (7,8) and (-4,9). Put your answer in fully simplified point-slope form, unless it is a vertical or horizontal line.

Answer 1

(7,8) (-4,9) have a line through them with slope = difference in y over difference in x

= (9-8)/(-4-7) = -1/11

point slope form of the equation is:

y-8 = (-1/11)(x-7)

or

use the other point

y-9 = (-1/11)(x+4)
