Answer:

Here is a proof

Angle DEF = angle ABC

A transversal cutting two parallel lines makes alternate exterior angles equal

Sum of measures of angles 1 and 2 = 50° + 48° = 98° = measure of angle DEF = measure of angle ABC

But since s bisects angle ABC, then angle 4 = 98 / 2 = 49°

But angles 3 and 4 are vertical angles....therefore.... measure of angle 3 = 49°

What is the equation of the graphed linear model? y = x +

timofeeve [1]

Answer:

y = - 2x + 110

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 )

To calculate m use the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 110) and (x₂, y₂ ) = (20, 70) ← 2 points on the line

m = $\frac{70-110}{20-0}$ = $\frac{-40}{20}$ = - 2

the line crosses the y- axis at (0, 110) ⇒ c = 110

y = - 2x + 110 ← equation of line
