Question 10 (5 points)

What's the equation of the graph shown above?

A) 3x - 4y = 4
B) 4x - 3y = 4
C) 3x - 4y = 1
D) 4x - 3y = 1

Answer 1

A. A) 3x - 4y = 4

Explanation:

Slope: m = (y2-y1)/(x2-x1)

m = (-4 - 2)/(-4 - 4)

m = -6/-8 = 6/8 = 3/4

y = 3/4x + b

2 = 3/4(4) + b

b = -1

y = 3/4x - 1

4y = 3x - 4

3x - 4y = 4
