Question

Which system of equations could be used to solve for the point of intersection of the lines on the graph? A) y = 3 4 x + 1 and − 4 3 x + 9 B) y = 3 4 x − 1 and − 4 3 x + 9 C) y = 3 4 x − 1 and − 3 4 x + 9 D) y = 4 3 x − 1 and − 4 3 x + 9

Answer 1

Answer: The answer is B)

Step-by-step explanation:

The slope of the blue line is  

3

4

, and the y-intercept is −1; therefore, the equation for the line is y =

4

x − 1.

The slope of the black line is −
