its my last question(i promise) please help me

OpenStudy (anonymous):

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 8x and y = 2x + 2 intersect are the solutions of the equation 8x = 2x + 2. (4 points) Part B: Make tables to find the solution to 8x = 2x + 2. Take the integer values of x between −3 and 3. (4 points) Part C: How can you solve the equation 8x = 2x + 2 graphically? (2 points)

OpenStudy (anonymous):

for Part A : if you sketch the graphs y=8x and y=2x+2 on the same coordinate system you will see that there are points where the 2 lines intersect. Those will be the points where the y value of the first funtion is exactly the same as the y value of the other function namely y=8x is exactly y=2x+2 , so you can write it like 8x=2x+2 , think of the first one as y1 and the second one as y2 . The points where the graphs intersect are points where y1=y2. for Part B: I'm guessing you have to solve it numerically , I will let you do that yourself for Part C: same as part A , just draw the graphs and check for points where the 2 lines meet Hope this helps : ))

YES, but i can not draw a graph for my answers,
