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
