Answer:
Slope: 0
Step-by-step explanation:
We have to find the slope of the line with the given points.
To find the slope, we would use the slope formula: m = y2-y1/x2-x1, where as "m" is the slope.
Plug in your coordinates and solve.
Solve:
m = -7 - (-7)/-2 - 4
m = -7 + 7/-2 - 4
m = 0/-6
Divide -6 from 0.
m = 0
You would notice that we have a "0" in our slope. There is no "rise" in the slope.
This means that the slope of our line would be 0.
Sin x =cos 19
X =sin^1(cos 19)
X=71
