Consider the graph for the equation y = -x + 4. Which equation, when graphed with the given
equation, will form a system that has one solution?
y = x + 4
y = -x + 4
y = -x - 8

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
