B & C I believe, not too sure about the “B” but ik C for sure

Jus plot the points in then draw a line through them.
I will attach a graph example of it
The slope is the rate of change
You can find it in two ways
1: visually, draw a triangle and count from vertically to horizontally
2: slope formula - I will show it this way
(Y2-y1)/(x2-x1)
Given points (3,12), (4,16)
(16-12)/(4-3) = 4/1 = 4
The slope is 4
The slope represents the $ per hour. In this case, the wage is $4 per hour.
In this equation you have 3m+3=15 or 3m+3=-15. Solving for m on both you get m=4 or m=-6. The answer is D.
So an equation of any line is y=mx+b.
We know that the m, or slope, equals 3.
y=3x+b
Now we find the b, or the y-intercept, by substituting the x and y values into their places.
4=3*1+b
4=3+b
b=1
Now that we have the y-intercept, we just substitute the m and b into the equation and receive our final answer:
y=3x+1
