solve each system of equations by graphing

y=x+1
y=3x-7

1 answer

this is an easy one to graph.

just pick some values for x or y and solve for the other value

what are you having trouble doing?

we can't graph it for you.

for y = x + 1
x = 0, y = 1 (0,1)
x = 1, y = 2 (1,2)
x = 2, y = 3 (2,3)
x = 3, y = 4 (3.4)
x = 4, y = 5 (4,5)

for
y = 3x - 7
for x = 0, y = -7 (0,-7)
for x = 1, y = -4 (1,-4)
for x = 2, y = -1 (2,-1)
for x = 3, y = 2 (3,2)
for x = 4, y = 5 (4,5)

plot points for each and solve
