A pair of linear equations is shown:
y = −x + 1
y = 2x + 4
Which of the following statements best explains the steps to solve the pair of equations graphically?
On a graph, plot the line y = −x + 1, which has y-intercept = −1 and slope = 1, and y = 2x + 4, which has y-intercept = 2 and slope = 4, and write the coordinates of the point of intersection of the two lines as the solution.
