30pts umm. I don't understand.

Step-by-step explanation:

70⁰

If you will look at the protector then you will see the J is indicating 70⁰. Thus, the measure of angle JHG is 70⁰

70°

Step-by-step explanation:

You have to count the degrees from right to left. You can also your common sense that an angle that much is less than 90°.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
