Answer: -3
Step-by-step explanation: m= -5-7/2+2=-12/4=-3
M=-3

V = A*h / 3
A = 5*12 / 2 = 60 / 2 = 30 m²
h = 9 m
________________
V = 30*9 / 3
V = 10*9
V = 90 m³
K can be any negative value if you want the line to be descending. k < 0
Ok, so the best way to start off solving this would be to find the y intercept.
The y intercept is the point that y is on when x is at 0
So when x (the horizontal axis, left to right) is at 0 the y axis (vertical axis, top to bottom) is at 3
That gives this equation a y intercept of 3, and because it is positive it will be plus 3
next we'll solve for the slope, the slope can be found using them formula (y2-y1)/(x2-x1)
We can use any two points on the line. So we'll use the points; (0,3) and (2,4)
So we plug these points into the equation, and the equation looks like...
(4-3)/(2-0)
So 4-3= 1
and 2-0=2
We set the slope up in rise (y) over run (x)
So the slope is 1/2
1/2 is equivalent to half.
So the slope of the line is .5x or 1/2x
with a y intercept of 3
So the equation would look like
y=.5x+3
or
y=1/2x+3
Answer choice C matches the equation that we got.
So your answer is C
