What equation is shown by the graph below?

y=x+4

Step-by-step explanation:

First, if you want to put the equation into slope intercept form (y=mx+b) you can easily find the b value by seeing that the graph crosses the y axis at (0,4) meaning the y-intercept is 4 (the +4). Next, to find the slope, you can  take any two points on the graph (for this example I'll use (2,6) and (4,8)) and plug them into the formula to find the slope to get a slope (m value) of 1.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
