Answer:
100
Step-by-step explanation:
Since l and r Parrell lines that means the measure of 4 is 80 since there vertical angles. And then 1 and 4 needs to be supplementary which means the two angles combined equals 180. so 180-80=100
so 1s angle measure is 100
10? If it’s y=Mx+b in the equation b = y intercept so it would be 10 let me know if it’s wrong
Answer:
0
y = -2
Step-by-step explanation:
The formula for the slope is (in general) Δy / Δx Since the value of y does not change (I'm assuming we are talking about AB), the slope is (-2 - - 2) / (2 - -2) = 0/4 = 0
So the equation of the line is
y = mx + b
m = 0
y = 0*x - 2
y = - 2 <<<< Equation
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite (number), sign change, and negation.
