James needs 50 tons of dirt for a large construction project. He already has 3 tons of dirt at the construction site. Each dump truck can transport 8 tons of dirt. How many trips does the dump truck need to take to reach 50 tons of dirt?A.
5
B.
6
C.
7
D.
8
Answers
Minimum number of trips the truck will need to take=47/8
=5.875
But since the truck cannot actually take 5.875 trips, it will take the next whole number of trips so it will take 6 trips.(B)

A) Yes, because the graph of the equation is a straight line.
B) No, because the graph of the equation is not a straight line.
C) Yes, because the graph of the equation passes through the origin.
D) No, because the graph of the equation does not pass through the origin.
Answers
Answer:
Option D is correct that is No, because the graph of the equation does not pass through origin.
Step-by-step explanation:
We have been given the equation:
y = 4x+4
The direct proportion means if equation follow: y=mx where m is the proportion or can say equation passes through origin.
Here, equation is y=mx+c not y=mx
In y=mx
We can see if x increases y will increase
And if x decreases y will decrease.
Therefore, Option D is correct that is No, because the equation does not pass through origin.

Step-by-step explanation:
1) I know that the equation for slope is y2-y1/x2-x1. For number one I first found two points of the graph which is (0,3) and (2,4) (not sure if I see it correctly, its kind of blurry). I decided that (0,3) would be my y1 and x1 and (2,4) will be my y2 and x2. I later plugged the number in the equation and got 4-3/2-0 which the answer turns out to be 1/2.
2) For the rest of the questions it is kinda the same business as question 1. For question two I chose two points out of the table which wrer (-1, -12) and (1,-8) and plugged them into the equation and got -8-(-12)/1-(-1) which the answer turns out to be 2.
3) similar to question 2. The two points(2,-6) and (-4,-3) are given to you. so I plugged them in again and got -3-(-6)/-4-2 which the answer turns out to be 3/-6 into 1/-3.
4) Same with question 1 find two points of the graph. I chose (0,3) and (1,1) (again might not be accurate it's kind of blurry) I plugged them into the equation again and got 1-3/1-0 which equals -2.
Just always remember y2-y1/x2-x1=m is the equation for slope.
(m is the variable for slope)
