Find the gradient/slope of Line A:

(3-2)÷(-1-4)

=-0.2

Therefore, the gradient/slope of line B is 5

Using the equation y-y1=m(x-x1) we can find the equation of line B

y-7=5(x-3)

y= 5x-8

Sub in a random value for y (eg. y=2)

2=5x-8

5x=10

X=2

so (2,2)

<span>The length of a rectangular prism is 5 more than twice the width w. The volume of the prism is 2w^3 + w^2 + 5w. What's the simplified expression for the height of the prism
</span>
<span>V=f(w)
</span><span>2w^3 + w^2 + 5w
</span><span>v=w^2*l
</span><span>svl l=v/w^2
</span>
<span>V=w^2*(2*w+5)
</span>
<span>2w^3 + w^2 + 5w=w^2*(2*w+5)
</span><span>(2*w+5)= (2w^3 + w^2 + 5w)/w^2
w=5/4</span>
