Answer 1

A pair of linear equations is shown below:

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. 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 = 1 and slope = 4, and write the coordinates of the point of intersection of the two lines as the solution. 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 = 2, and write the coordinates of the point of intersection of the two lines as the solution. 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 = 4 and slope = 2, and write the coordinates of the point of intersection of the two lines as the solution.
