Answer:

4/5x+2/5 = y

Step-by-step explanation:

(-3, -2) & (2,2) - given points

1. Find Slope

2-(-2) / 2-(-3) = 4/5

m=4/5

2. plug in points to find b

4/5(x)+b=y : mx+b=y (slope intercept form)

4/5(2)+b=2

8/5+b=2

2 - 8/5 = b

10/5 - 8/5 = b

b=2/5

Therefore: 4/5x + 2/5 = y

The proof, with a missing reason, proves that the measure of angle ECB is 54°.
aniked [119]

Answer:

Midsegment of a Triangle Theorem

Step-by-step explanation:

In\: \triangle ADE\\m\angle A + m\angle D + m\angle AED = 180°\\\therefore 90°+36°+m\angle AED= 180°\\\therefore 126° +m\angle AED = 180°\\\therefore m\angle AED = 180°-126°\\\therefore m\angle AED = 54°\\

In\: \triangle ADE, D and E are mid points of sides AB and AC respectively.

Therefore, DE || BC

Hence, by Midsegment of a Triangle Theorem

m\angle ACB = m\angle AED =54°(corresponding\:\angle 's) \\\therefore m\angle ECB = m\angle AED =54°(\because A - E - C)

What is the slope and y intercept of this graph
castortr0y [4]
The y-intercept is the value of "y" when x=0.

Answer. y-intercept= 4

Given two points (x₁,y₁) and (x₂,y₂) the slope passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)

For example :
we can consider the points (0,4) and (4,0)
m=(0-4)/(4-0)=-4/4=-1

Answer the slope of this line would be m=-1
