these problems been confusing me for a while- if you could please help me with the answers that would be amazing.

Answer:

Angle 1 = 85*

Angle 3 = 85*

Angle 4 = 95*

Angle 5 = 85*

Angle 6 = 95*

Angle 7 = 85*

Angle 8 = 95*

Step-by-step explanation:

Since angle 2 is 95*, angle 4 would be the exact same. Now you add 95+95=190 and subtract that from 360. 360-190=170. Then divide 170 by 2= 85 to get the measurements for 1 and 3.

Well according to the slope intercept equation.

Y = mx +/- b

The slope is the value m
The y intercept is b

To graph the function, one sure way to do it is simply make a table of values picking any x values that fall within the graph space, and finding out the resulting y values and using the points to graph.

For instance for the first graph, if x = 0, y = 5, that is one possible point. Keep on choosing x values to graph.
