Question

35 points | Hi, could I have some help? :)

I am helping my sis with homework, and my calculations don't add up. So, could someone help me, please?

Okay, so. The question is asking to graph the following equations:

y = 30x
y = 20x+125

I understand that the slopes are different. Therefore there is only one solution. Now, the real question is, did I graph these correctly?

The slope of equation one is 30 (m=30), and in two, 20, m=20. The y-intercept of equation one is 0, respectively, and the y-intercept of equation two is 125. I made the interval of her graph by 25; so, 25...125...225, so-on. And the x-axis by ones, so, 1...2...3...4.......................10, you know.

I don't understand how to upload a file, so I'm asking if someone could graph these equations and see where they intersect.

Thank you xoxoxoxo

Answer 1

For the first equation, you start at 0 and go by 30. The second one you start at 125 then go up gradually by 20 like you did for the first equation. Hope it helped
