(4,5)=(x2,y2)

d=?

d= $\sqrt(4+2)2 + (5-1)2\\\sqrt(6)2+(4)2\\\sqrt36+16\\\sqrt52\\$

The equation for working out the slope of a linear line is: $\frac{y_2 - y_1}{x_2 - x_1}$ , where x and y are the coordinate pairs.

So just pick two of the purple dots on the graph and fill in the equation.

I'll pick the dot that's (-4, 1) and (4, -7).

Now I just do $\frac{7 - 1}{4 - -4}$ , which is just $\frac{3}{4}$ when simplified.
