Answer:
-a/b
Step-by-step explanation:
ax+by=c
First get the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)
Subtract ax from each side
ax+by -ax=-ax +c
by = -ax+c
Divide each side by b
by/b = -ax/b + c/b
y = -a/b * x + c/b
The slope is -a/b and the y intercept is c/b
We want the line parallel so it has the same slope, -a/b
Say the first number is x, you would then have x and 6x and then x + 100. If you add all these together you get 8x + 100 = 708. You then subtract both sides by 100 and get 8x = 608. Divide both sides by 8 and you get 608/8 which = 76.
Answer:
x=4
Step-by-step explanation:
divide the x-value by the y-value. 9/36 =0.25.
0.25*16=4
x=4.
