Question

X y

-1 3
0 5
1 7
2 9

1. What is the slope? m=
2. What is the y-intercept? b=
3. Write the equation in slope-intercept form:

Answer 1

1. m=2
2. (0,5)
3. 2x+5

Explanation:

The slope is achieved through (5-3)/((0-(-1)) which is 2. The y-intercept is just where x=0 on the equation so (0,5). 3. Put it all together in y=mx+b to get 2x+5. Hope that helps!
