Answer:
Slope = -9/2
Two points are (-2,9) and (2,-9)
Step-by-step explanation:
The two points the equation should go through are (-2,9) and (2,-9), (Dark Green and Light Blue).
The slope-intercept is calculated using the two points above;
-9 - 9 = -18
2 - (-2) = 4
Slope = -18/4 or -9/2

Answer:
20 degrees
Step-by-step explanation:
we can consider 33 to be the radius of a circle.
31 would then be the cos of the angle in that circle.
the regular cos function is defined for the standard circle with radius 1. so, that would be multiplied by 33 for this circle here.
31 = cos(?) × 33
cos(?) = 31/33 = 0.9393...
? = 20.05 ≈ 20 degrees
