The slope of a graph is rise over run. So count how many units up you move and put that over how many units right you move. If you are moving down or to the left it would be negative.
Answer:
It is a vertical line
Step-by-step explanation:
Find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(1 - 9) / (-7 + 7)
-8/0
= undefined
Dividing by 0 gives you an undefined number. This means that the slope is undefined, and the line is a vertical line.
I am not sure what the question is but here is how you use trig functions:
sine of the angle = side opposite the angle ÷ hypotenuse
cosine of the angle = side adjacent to the angle ÷ hypotenuse
tangent of the angle = side opposite the angle ÷ side adjacent to the angle
