Answer:
y = - 2x - 4
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 ) = (- 2, 0) and (x₂, y₂ ) = (0, - 4) ← 2 points on the line
m = =
=
= - 2
the line crosses the y- axis at (0, - 4 ) ⇒ c = - 4
y = - 2x - 4 ← equation of line
Two angles are supplementary if their sum is 180 degrees.
Here we are given:
Angle GHI measures (28x + 40)° and angle JHI measures (7x)°.
Sum of angle GHI and JHI is 180.
dividing both sides by 35,
x=4
Now let us find angle JHI
angle JHI = 7x = 7*4 =28
Answer : Angle JHI is 28 degrees.
