Question

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?

Answer 1

Oh let me fix that

Answer 2

a. 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.

b. 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.

c. 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.

d. 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.

Answer 3

Those are the solutions
