What is the solution of the system? Use a graph. y = x + 5 y = –5x – 1

sam (.sam.):

y = x + 5 will have y-intercept on 5 y = –5x – 1 will have y-intercept on -1

sam (.sam.):

Now you'll simply use any x values that's reasonable like -2 and 0 substitute into those equations to find the y value for plotting

i'm confused

sam (.sam.):

Do you understand the y-intercepts?

sam (.sam.):

y = x + 5 will have y-intercept on 5 y = –5x – 1 will have y-intercept on -1 because y = mx +b and b is the y-intercept
