Step-by-step explanation:
subtract the whole equation by 85 on both sides to get v by itself on the left side
85-85-v=213-85
-v=128
Now we divide the whole equation by negative 1
-1v/-1=128/-1
v=-128
Hope that helps :)
Heyyy... I am so sorry about the answer above... some people just want points.... and I am also sorry I don't know the answer
a.
Solution Given:
Slope of the line passing through the point is
m=
<u>slope=-2</u>
b.
Solution given:
equation is
2x-5y=-10
2x+10=5y
y=2x/5 +10/5
y=2/5 x +3
comparing above equation with y=mx+c
we get
m=2/5
<u>slope=2/5</u>
c.
Slope of the line passing through the point is
m=
-4=
-4=10/-x
doing criss cross multiplication
-4*-x=10
4x=10
x=10/4
x=5/2
<u>slope=5/2</u>
d.
we have
equation of line passing through the one point is
y-5=-7(x-(-1))
y=-7(x+1)+5
y=-7x-7+5
<u>y=-7x-2 is a required equation:</u>
Answer:
If it's supposed to have no solution, I think you can just use an extreme number, like -30 or something.
