Question

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?

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 1

A nd B are wrong cuz the slope or intercepts are stated wrong

Answer 2

y = mx+b
m = slope
b = y intercept

For example, y = 7x+12 has slope m = 7 and y intercept b = 12

Answer 3

okay

Answer 4

C?

y = mx+b
m = slope
b = y intercept

Based on this payt, which one has stated the correct slope and intercepts?

Answer 6

For c, is the y intercept -2?

Answer 7

yes

Answer 8

¨which has y-intercept = −2 and slope = 2¨

Answer 9

For the equation y=2x+4, is the y intercept -2?

Answer 10

oh no

Answer 11

so c isnt my answer then

Answer 12

it has to be D

Answer 13

Yes correct
