Step-by-step explanation:
Given

Required
The line graph
First, consider the following points on the graph.
First, calculate the slope.
undefined
Since, the slope is undefined; we simply consider only the value of x.
The line equation is:
Answer:
B
Step-by-step explanation:
Notice that the y intercept is 125 and that each time week it goes down by 25 meaning the slope is equal to -25
this means our equation is
-25x+125=y which is the same as b
Answer:
Measure of angle ADC is 70°
Step-by-step explanation:
So, we know that the overarcing angle BDA equals 110°. And then, we have these two equations that split up this overarcing angle. To solve for x, all we need to do is say is that the sum of these two equations are equal to 110°
2x+10+3x+25=110
Combine like terms
5x+35=110
Subtract 35 from both sides
5x=75
Divide by 5 on both sides
x=15
Now, to find the measure of angle ADC, simply plug 15 in for x on that equation:
3(15)+25
So, the measure of angle ADC is 70°
72 I am guessing because you divide by 3
