Question

Explain, how you can solve the pair of equations graphically. Wright the slope and y- intercept for each equation that you will plot on the graph to solve the equations

Answer 1

You can solve the pair of equations graphically by finding where the two lines intersect/meet. The point where they intersect is the solution to both of the equations.

Slope-intercept form: y = mx + b    

(m is the slope, b is the y-intercept, or the point where x = 0 ---> (0 , y))

y = 7x - 9

m = 7

y-intercept = -9     ----->    (0, -9)

y = 3x - 1

m = 3

y-intercept = -1  ------>  (0, -1)

I'm not really sure what the last sentence of the question is asking, so you could clarify the question if you need help
