Question 857781: Can you help me to solve this equation using graphing and write no solution or infinitely many solutions where appropriate.
y + 1 = 2/3(x - 3)
x + 3y = 9

You can put this solution on YOUR website!
The intersection of those two, by graphing?

y+%2B+1+=+%282%2F3%29%28x+-+3%29
Point-Slope form.
An included point is (3,-1), and slope is 2%2F3.

x+%2B+3y+=+9
Standard Form.
x-intercept is 9 and y-intercept is 3.

That is enough to graph each line and then locate the intersection, or the solution for the system of the two equations.
