Answer:

B

Step-by-step explanation:

From -1 to 1 on the x-axis, the graph has to be below the x-axis because then the y-values will be negative.

Answer choice C & D have the graph above the x-axis in that interval, so it's positive instead of being negative. We can cross out those two answer choices.

The reason why answer choice A isn't correct is because at 1, the graph line is above the x-axis, since the brackets [-1, 1] means it includes -1 and 1.

So the only answer left is B.

Hope that helps (●'◡'●)

A line contains the two points plotted in the coordinate plane below.
Andrew [12]

Answer:

The slope would be 3.

Step-by-step explanation:

The formula for finding slope is \frac{y1-y2}{x1-x2}
We can plug these numbers into the equation by doing \frac{1--5}{2-0}
1--5 is equal to 1+5, which is 6.
2-0 is equal to 2.
\frac{6}{2} is 3, which is how you get your answer.
I hope this helps! :)

Answer:

y intercept=15 and slope is 3

Step-by-step explanation:

Ok so for this one we know the y intercept is 15 because the y intercept is wherever x=0 and in the table when x=0 y=15

to find slope we use (y2-y1)/(x2-x1) which when we put points (0,15) and (1,18) in for would be:

(18-15)/(1-0)

3/1

= 3
