TEST TOMORROW
Objective
Find slope, y-intercept, graph using slope and y-intercept, and write equations using slope and y-intercept.
Review FAQ
How do you find the rate of change when they don't give you points?
A line is made up of infinite points so they really did give you points, you just have to look harder. Find a place where the line and 2 grid lines intersect and put a dot there- that is a point you can use.
How can I find the unit rate for a rate of change like 3/4?
You do this the same way we found unit rate for anything, divide the numerator and denominator by the denominator. You will end up with 0.75/1.
What's the deal with #4-9 on the practice test?
You need to identify the slope on those. The instructions printed weird.
Your goal is to find the slope. The easiest way would be to get the problem in Slope-intercept form or y=mx+b. You do this by solving them for y or, in other words, getting y all alone on one side of the equal sign. Once your problem looks like y=mx+b but with numbers for m and b, the number in m's place is the slope.
