Step-by-step explanation:
The equation is y = mx +c
since we know that m is the gradient, we look at the two points on the line and draw two lines as shown in the picture above.
the yellow line goes down 2 squares
and the red line goes left once
so it's 2 over 1
2÷ 1 = 2
so the gradient equals 2
now for the c
c means the y intercept. so all you have to do, is find where the line hits the y axis.
In this case it's -3
lastly, we need to put it in the equation
y= mx +c
y= 2x -3
and that should be all
I hope that helped xx
