Answer:
C. No solution
Step-by-step explanation:
Eliminate the y terms by multiplying by 28 and 4
28(-9x-4y=1)
4(63x+28y=-6)
This forms
-252x-112y=28
252x+112y=-24----------------------add the y terms to eliminate them
-252x+252x=28+-24
0=4--------------------------x terms also eliminated
No solution
Answer:
360
Step-by-step explanation:
18.5 you’d add 2.5 to 16 since 12.5 - 10 is 2.5 hope this helps
<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)
