Write a linear equation y=mx + b to represent the graph:

Step-by-step explanation:

Firstly you need to understand some variables in the equation.

m= gradient

b= where the line cuts the y axis

Now we can try using any coordinate in the graph and see what the question becomes.

at a point where :

Y= -2 and X= 1

The equation becomes

-2=m(1)+-5

Then:

-2+5=m

m=3

So, we can now write the equation in the form of y=mx+b as follow.

Y=3x-5

x= 149. 24+7=31. 180-31=149
