Question

A line is drawn through (-7, 11) and (8, –9). The equation

y - 11 = - 4(x + 7) is written to represent the line. Which
equations also represent the line? Check all that apply.
3y = - 4x + 40
4x + y = 21
4x + 3y = 5
-4x + 3y = 17

Answer 1

4x + 3y = 5

Explanation:

Gradient = -9 -11/ 8 + 7

= -4/3

Equation of the line...

y = mx + c

y = -4/3(x + 7) + 11

Multiplying through by 3...

3y = -4x - 28 + 33

3y = -4x + 5

4x + 3y = 5
