Question

Write an equation of the line below.

Answer 1

I assume you mean the equation OF the line below.

The equation for a straight line has the general form
y=mx+c

m is the gradient of the line
c is the offset and is given by the value of Y where the line crosses the Y axis

The gradient is given by (change in y)/change in x

You can see that the line passes exactly through (2,5) and (0,-1) so you can work out the gradient from those 2 points (be careful about the minus signs)

you can also get the value where the line crosses the Y axis

So write the formula y=mx+c using the values you got from above...
