Answer:
C
Step-by-step explanation:
It was just in my notes....
<span>You need to know two points on your line, in order to find the slope.
If you're given the y intercept, that is one point, (0,a) where a is the y intercept.
If you're given the x intercept, that's another point, (c,0) where c is the x intercept.
You could also be given points on the line that aren't an x or y intercept. Let's call these points (r,s) and (j,k).
To find the slope of the line, you need just two points. Take the
difference of the y coordinates, and divide by the difference of the x
coordinates to solve for the slope.
Using our two generic points (r,s) and (j,k), we would solve for the slope m as follows:
m = (s-k) ÷ (r-j)
Hope that helped! </span>
The x value will change to y avlue and vice versa
so x---> y and y---> x
(x,y) --> (y,x)
B
Answer: $15.94
Step-by-step explanation:
You divide 23.91 by three, then subtract using the previous answer which was 7.97. 7.97 was 1/3 of 23.91. When subtracted you get, 15.94.
Answer:
1. (5 * 6) + 10 / 8 = 8
