Question

Y = 2x − 1

y = 4x − 5

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:

part A y = 2x "-1" the slope is 2/1 means it will be up 2 right 1 or down 2 left 1 the slope positive the y-int is "-1" y = 4x "-5" the slope is 4/1 means it will be up 4 right 1 or down 4 left 1 the slope positive the y-int is "-5" part B the solution to this is (2,3)

Answer 2

part A
y = 2x -1
the slope is 2/1 means it will be up 2 right 1 or down 2 left 1 the slope is positive
the y-int is -1

y = 4x -5
the slope is 4/1 means it will be up 4 right 1 or down 4 left 1 the slope is positive
the y-int is -5

part B
the solution to this is (2,3)
