Question

What is the answer to this

Answer 1

y = -1.5x - 1

Answer 2

y = -1.5x - 1

Explanation:

We can use the general equation of y = mx + c to form our linear equation as seen on this graph.

Choosing two points on the graph (I will choose 0,-1 and 2,-4) we can find the gradient, m, as the distance between these points

`(Rise)/(Run) = ((-1)-(-4))/((0)-(2)) = (3)/(-2) =-1.5`

We can find the c value by seeing where the graph cuts through the y-axis

This point is -1

Therefore our equation is y = -1.5x - 1

Alternatively, you could write it as
`y= -(3)/(2) x - 1`
