The slope intercept form is:


y=mx+b

Where

m is slope

b is y-intercept (y-axis cutting point)

Let's find the slope (m) using the 2 points given. The formula is:


m=(y_2-y_1)/(x_2-x_1)

Let's put the points (0,2) and (2,-4) and find the slope:


\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m=\frac{-4-2_{}}{2-0_{}}=-(6)/(2)=-3 \end{gathered}

The y intercept, y axis cutting point, is directly taken from the graph as "2".

Thus, now we can write:


y=-3x+2
