How many solutions does the system have y=2x-1 y=2x+6

no solutions

Step-by-step explanation:

Given the 2 equations

y = 2x - 1 → (1)

y = 2x + 6 → (2)

Substitute y = 2x - 1 into (2)

2x - 1 = 2x + 6 ( subtract 2x from both sides )

2x - 2x - 1 = 6 ( add 1 to both sides )

0 = 7 ← not possible

Thus the system has no solution

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
