The slope-intercept form:

m - slope
b - y-intercept → (0, b)
We have the points (-9, -9) and (0, 1) - y-intercept → b = 1.
Calculate the slope:

Answer: 
The function of f(x)=-x+4x-3 is 3x-3. I hope this helps. :)
We know, Slope = y2-y1 / x2-x1
& also, slope = rise / run
In short, Your Answer would be Option A & C
Hope this helps!
Aloha, thanks for using Brainly.
Step-by-step explanation:
For 1. 7/8 is 90 percent so .90
For 2+. Add the bottom together, whatever you get divide top by bottom.
The others you just divide them by each other.
