Write slope intercept equation passing through (-5,0) and (0,4/5)
pav-90 [236]
First find the slope by calculating rise (change in x) over run (change in y).

(4/5)-0/0-(-5)

(4/5)/5=0.16

The y intercept is 4/5. We know this because y interceot is the value of y when x is 0.

Then plug this into y=mx+b where m is slope andb is y intercept.

Final answer: y=0.16x+0.8 or y= 4/25x+ 4/5

Need help idk how to slove this
Gemiola [76]

Hi!

I'm not sure how to slove this, but I do know how to solve it ;D

<h3>We can't know the exact value of y, but we can isolate y on one side. First, multiply by z on both sides. </h3>

\frac{x+y}{z*z}=3*z

x + y = 3 * z

<h3>Now subtract x from both sides.</h3>

x - x + y = 3 * z - x

<u>y = 3 * z - x</u>

<h2>The answer is y = 3 * z - x</h2>

Hope this helps! :)
