Question 295807: Given the pair of linear equations in two variables:
Find the x- and y-intercepts (if any) for each line.
Plot those intercepts, and graph the two lines on the same chart.
Apply elimination or substitution to find the coordinates of the point of intersection (if there are no solutions or infinite solutions, state this).

x + 9y = 79
-7x + 9y = 23
Please and Thank you

You can put this solution on YOUR website!
subtract equation 2 from equation 1
8x=56
x=7
use equation one
7+9y=79
9y=72
y=8
(7,8)
