Hi the answer is 60 but the picture will show you the work!!
Answer:
Slope:-63
Y-intercept: (0,825)
Step-by-step explanation:
Slope= y2-y1 ÷ x2-x1
321-699 ÷ 8-2
-378 ÷ 6 =-63
Y-intercept:
y=-63x+b
to get b (y-intercept) plug in one of the points and solve.
699=-63(2)+b
699=-126+b
699+126=-126+126+b
699+126=0+b
825=b
Answer:
Option B is correct
Step-by-step explanation:
Given that:
and 
are supplementary.
prove that: 
It is given that:
and are supplementary.
By definition of supplementary
⇒
.....[1]
From the figure, you can see that:
and 
are also supplementary.
⇒
.....[2]
By [1] and [2] we have;
⇒
Simplify:
Since ∠2 and ∠3 are corresponding angles.
Corresponding angles states when the two lines are parallel, then Corresponding Angles are equal and vice versa.
by definition we have;
proved!
Pa18 has the right answer
First the equation needs to be set to "y" to find the total amount of miles traveled:
y=
Then you know he has already gone 3.5, this is a constant and can be added to the graph immediately
y=3.5
Then you know every two hours he can cover 100 miles, which means 50 miles per hour or 50 per x, so add 50x to 3.5 to show that he will go 3.5 miles plus 50 miles for every hour he is traveling.
y=3.5+50x
