Which equation best represents the relationship between x and y in the graph
iogann1982 [59]

The equation of the line is  y= 3 - 2x.

<h3>What is equation?</h3>

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.

Given:

Coordinates (0, 3) and (2, -1)

So,

slope = -4/2=-2

and equation of line is

(y- y1) = m (x- x1)

y-3 = (-2)(x-0)

y-3 = -2x

y= 3 - 2x

Hence, the equation of line is y= 3 - 2x.

andy constructed a triangle angle 1 and 2 are the same but angle 3 has a measurement of 100 degrees what is the measurement of a
attashe74 [19]
The triangle has one angle of 100 degrees, and the other two are equal. 
We know that the angles of a  triangle always add up to 180. To find the measurement of angle 1 and 2, let's solve for this equation. 
2x + 100 = 180, where x=angle 1 = angle 2. Subtract 100 from both sides
2x = 80                                                           Divide both sides by 2
x = 40
