Question

PLZ HELP!!!! A pair of equations is shown below: y = 6x − 4 y = 5x − 3 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

Explanation:

y = 6x − 4

y = 5x − 3

A: chose a value for x(input) and get the out put (y) because the equation already in the slope intercept mode:y=mx+b

x y=6x-4 y=5x-3

1 y=2 y=2

2 y=8 y=7

0 -4 -3

slope :

y=6x-4 slope is 6 y intercept(0,-4)

y=5x-3 slope is 5 y intercept (0,-3)

solution of the pair of equation is the point of intersection :

6x-4=5x-3

6x-5x=-3+4

x=1 and y=6x-4 ⇒ y=6-4=2
