When you plot te points on a graph you notice it's a parabolaThen its equation is y= x²+bx+c

Plug x & y by their respective values (2 different points are enough) & you will get a system of equation with 2 variables a & b

After solving them you will get a=8/3 & b=-1/4 & c=-5

Hence the equation is y = (8/3)x²-1/4x+5

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\
m=\dfrac{2-(-3)}{-1-6}\\
m=\dfrac{5}{-7}\\
m=-\dfrac{5}{7}\\$
