Answer:

Step-by-step explanation:
Slope-intercept form: y = mx + b
Slope formula: 
Given points: (3, -7), (7, 2)
(3, -7) = (x1, y1)
(7, 2) = (x2, y2)
To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.
First, let's find the slope. To do this, input the given points into the slope formula:

Simplify:
2 - (-7) = 2 + 7 = 9
7 - 3 = 4

The slope is
.
To find the y-intercept, input the slope and one of the given points(in this example I'll use point (7, 2)) into the equation and solve for b:



The y-intercept is
.
Now that we know the slope and the y-intercept, we can write the equation:

In 22, you're looking for the vertical height of the triangle. You're given the angle opposite the side you want to find (which I'll call

) and the length of the hypotenuse. This sets you up with the relation

In 23, you're given a similar situation, except now you're looking for the angle (I'll call it

) in the triangle opposite the side denoting the height of the airplane. So this time,
Melissa has 85 crayons because you do 36+49
I think the answer is 180 since 360/2=180
Answer:
390 minutes I do believe.
