Question

One of the equations represents the graphed line. Which equation is it ?

Answer 1

A

Explanation

Options remaining: A B C D

Step 1: look at the direction that the graph is going

The graph in increasing, its values gradually getting higher. This means that the graph will be positive, and we can eliminate the options with a negative slope

Options remaining: A B D


Step 2: Look at the y-intercept

The line crosses the y-axis at -4. That is also known as the y-intercept. So, we can eliminate the options without this as a y-intercept.

Options remaining: A D


Step 3 (final step): Look for slope

To find slope, do rise/run. This will bring you to the answer of 1/2. So, this will be used in the final equation.

Final option: A

Answer 2

A

Explanation:

the line goes through the point (0,-4) so that is the y intercept the the slope of the line is 1/2 because from (0,-4) it goes up 1 and to the right 2, so if u use the equation y=mx+b then u should get y=1/2x-4, so the answer is a.
