Answer:
y- intercept = - 2.5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (5, - 25)
m = =
= - 4.5 , then
y = - 4.5x + c
To find c substitute either of the 2 points into the equation
Using (1, - 7), then
- 7 = - 4.5 + c ⇒ c = - 7 + 4.5 = - 2.5
y- intercept c = - 2.5

Using the sine ratio in the right triangle
sinΘ = =
, thus
Θ = (
) ≈ 51.1°
(5)
Using the tangent ratio in the right triangle
tanΘ = =
, thus
Θ = (
