Brainliest rewarded jamal drew the function below. which explains whether or not his function is linear? a. it is linear because it has a constant rate of change. b. it is linear because it does not have a constant rate of change. c. it is not linear because it has a constant rate of change. d. it is not linear because it does not have a constant rate of change.

A. It is linear because it has a constant rate of change.

Step-by-step explanation:

A straight line graph is possible between two variables x and y only if there is a constant rate of change

y = mx+b is the equation of a straight line in general and here we find rate of change of y with respect to x is constant m which does not depend on x or y.

In other words, throughout the domain a straight line has constant slope.

Here we find that the graph given is a straight line.

Hence option A is suitable answer

A. It is linear because it has a constant rate of change.

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
