Answer:
112.5
Step-by-step explanation:
25% of 450 = .25 x 450 = 112.5
I THINK IT IS B
B) D(X)= X-8x4
Answer:
Slope: ![-\frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B4%7D)
Y intercept: 7
Equation: ![y=-\frac{3}{4}x+7](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B3%7D%7B4%7Dx%2B7)
Step-by-step explanation:
The slope is found by doing the equation
. When looking at the first two points, it's shown that the rise (difference between the two y values) is -3 (since it decreased by 3) and the run (difference between the two x values) is 4 (since it increased by 4).
This gives us a slope of
.
The y intercept is found by looking at the y value when x = 0. In this picture, it is clear that it is 7.
The equation you want to use is y = mx + b , where b is the y intercept and m is the slope. Just plug in the numbers and you got your equation!
