Question

Which of the graphs below represent the graphical solution to the following system of equations? Look at attached file.
3x - 4y = 32
5x + 2y = 10

Answer 1

There are a couple of ways to answer this question.
one way is solve the equations, and look for the graph where the lines cross at that point.

another way is look at where the lines cross the y-axis (y-intercept), by putting x=0 and seeing what y is. look for the graph where the lines go through the correct y-intercepts.

or, look for the x-intercepts of each line (set y=0 and solve for x). look for the graph where the lines go through the x-intercepts.


or, try each (x,y) pair where the lines cross in the equations and see if they are true.
