Answer:
y = -5x + 6

Explanation:
The equation of line in slope-intercept form is:
y = mx + c
where:
m is the slope
c is the y-intercept

We are given that the slope = -5. Therefore, the equation becomes:
y = -5x + c

Now, we need to get the value of c. To do so, we will substitute with the given point (3,-9) in the equation and solve for c as follows:
y = -5x + c
-9 = -5(3) + c
-9 = -15 + c
c = -9 + 15 = 6

Based on the above, equation of line is:
y = -5x + 6

Hope this helps :)

Set up a right triangle model for this problem and solve by using the reference table trigonometric ratio that applies. Follow t

RSB [31]

In reference to the angle of elevation (41 degrees), the adjacent side is 60 and the opposite side is the unknown.
Using tangent ratio:
tan 41 = opp/60
60 tan41 = opp
opp side = 52.2yards
