What I would do for this problem, is move all the terms that don't contain m to the right side, and then solve.
m = 4/5.
Answer: y = -2x -2
Step-by-step explanation:
Making y the subject of the formula
Subtract 4 from both sides
⇒ y = -2 ( x - 1 ) - 4
y = -2x + 2 -4
y = -2x -2
Answer:
race run = 27.60 km
Step-by-step explanation:
given data
run = 5 %
race = 1.38 km
to find out
how long is the race
solution
we get here how long he race that is here
1.38 ÷ 5 % × 100
= 20
so
race run = 1.38 × 20
race run = 27.60 km
Answer:
This equation is in standard form, so to make graphing easier you need to put it in y=mx+b form or slope, intercept form.
Step-by-step explanation:
I have attached a photo of what the graph would look like.
However, in the future you should know how to turn this into a slope intercept equation.
-2x+7y=-21
+2x +2x
7y=2x-21
divide the entire equation by 7
y= 2/7x-3
That is a full equation in slope intercept form.
Hopefully this helps!
