Hello,
I have not done math in about 20 years and would like to help my daughter. This is my first post here.
I added an image of the problem. I am hoping that if you walk me through it might jog my memory.
Thank you for your help.
I'll get you started.
The slope of a line is the amount by which y increases when you increase x by 1. For a line, this will be constant, so you can just pick two values of x that differ by 1, find the values of y, and subtract. Or, you can use a formula that will have been taught.
The y-intercept of a line is the value of y when x is 0. Whether you are given a table or a graph, you can just read it from the data.
So, give it a try, and show us what you get. This will help you a lot more than just showing you the answers.
If I were you, I go a little farther than the problems ask you to, and graph both lines in each problem, so you can see visually the effects of the slope and y-intercept. That will give you more to talk about together.
If you don't have a textbook or equivalent to look at, you can start here (more links at the bottom):
