Please help me please !

For the first one:

y = 2/3x + 1

For the second one:

y = -5x + 4

Step-by-step explanation:

As you may already know, in the y=mx+b equation format:

m = slope

b = y-intercept

On the graph, it already shows the y-intercept, so you can automatically find your b in the equation.

And, the easiest, most quick way to find the slope by using a graph is to calculate using rise/run. So, by doing that you can calculate the equation.

Then, you can just leave the variables y and x alone.

Hope this helped!!

x+y=90

x=30-y=x

if you understand you will get the answer
