Answer: option D is the correct answer.
Step-by-step explanation:
The given pair of linear equations is
y = -x + 1
y = 2x + 4
We would compare both equations with the slope intercept form equation of a straight line which is expressed as
y = mx + c
Where
m represents slope
c represents y intercept.
Comparing the first equation,
Slope = - 1
y intercept = 1
Comparing the second equation,
Slope = 2
y intercept = 4
Therefore, the statement that best explains the steps to solve the pair of equations graphically is
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.
