Question

A pair of equations is shown below:

y = 7x − 9
y = 3x − 1

Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations. (6 points)

Part B: What is the solution to the pair of equations? (4 points)

Answer 1

Asking the Math Gods...

X=2
Y=5

Sub y=3x-1
[(3x-1)=7x-9]
Isolate x for (3x-1)=7x-9: x=2

for y=3x-1
Sub x=2
y=3*2-1 y=5
