Question

Write the equation of the line that passes through the give points (-1,11) and (3,-5)

Answer 1

y = -4x +7

Explanation:

The 2-point form of the equation for a line can be used.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (-5 -11)/(3 -(-1))(x -(-1)) +11 . . . . fill in values

y = (-16/4)(x +1) +11 . . . . . . . . . . . simplify some

y = -4x +7
