Question

A function f(x) is graphed.

What is the slope of the function?
m =
A.1
B.2
C.3
D.4
What is the y-intercept of the function?
b =
A.-2
B.-1
C.1
D.2
Which equation represents the graph of the function?
A.y=-x+2
B.y=x+2
C.y=2x+1
D.y=-2x+1

Answer 1

slope: B. 2
- this is because slope= rise/run
- the rise is 2 and the run is 1
-2/1= 2

y-intercept: C. 1
- this is where the line crosses the y-axis (the vertical line in the center)

equation: C. 2x+1
- this is in slope-intercept form; y=mx+b
- m is equal to the slope which we determined is 2
- b is equal to the y-intercept which we determined is 1

Answer 2

B, C, C
