Quiz about STAAR Algebra 1 Category 1 Review

Question 1

When it says the keywords directly varies or directly proportional. You can set up a proportion that looks like this:

$$\frac{y}{x}=\frac{y}{x}$$

Then solve the equation for the missing variable by using Menu 3, 1.

Accepted Answer

C

Answer

A

Answer

B

Answer

D

Question 2

To create a SLOPE-INTERCEPT FORM equation, start by creating a T-CHART on your paper and writing y=mx+b on both sides. Then, because it says PARALLEL, that means these equations will have the same slope so you can use the 1.2 given to you and plug it into both equations. Then, use the point (5, 0) which is written as (x, y) and plug it into the first equation. Then, solve for b using Menu 3, 1. Once you find the b, plug it into the second equation.

Question 3

When given two points you can find the slope by using the slope formula: $$\frac{y_2-y_1}{x_2-x_1}$$

or

Use a Lists & Spreadsheet, Data & Statistics, Menu 4, 6, 1. Which will give you an equation as y=mx+b and we know the m is the slope.
