Question

Graph the systems of equation on a piece of paper.what is the solution.

y = x-1
y= -2 + 5

A. (0,5)
b.(-1,4)
c (2,1)
d (3,2)

Answer 1

C

Explanation:

Assuming the lines are y = x -1 and y = -2x + 5, set them equal and solve for x.

x - 1 = -2x + 5

3x - 1 = 5

3x = 6

x = 2

Substitute x = 2 into one of the equations to find y.

y = 2 - 1

y = 1

The solution is (2,1).
