Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x + 2 intersect are the solutions of the equation 4x = 2x + 2. (4 points)

Part B: Make tables to find the solution to 4x = 2x + 2. Take the integer values of x between -3 and 3. (4 points)

Part C: How can you solve the equation 4x = 2x + 2 graphically? (2 points)

Answer 1

Answer 2

as the two curve intersects.......... their y co ordinate must be same at the point of intersection .....

Answer 3

i guess i get that but i am still confused

Answer 4

Answer 5

@xapproachesinfinity

Answer 6

I can help you in part C

Answer 7

okay :)

Answer 8

4x=2x+2
4x-2x=2
2x=2
x=1
Draw that on graph

Answer 9

answered

Answer 10

i cant add a graph it is flvs but i guess i can put that equation

Answer 11

thanks

Answer 12

if y co ordinates are same then ..... substitute the the values of y in in one equation to another....

Answer 13

for part a?
