Answer:

Step-by-step explanation:
<u>Point slope form</u>
y=mx +c, where m is the gradient and c is the y-intercept.
To find the gradient, use the formula below:


Substitute the value of m into the equation

To find c, substitute a coordinate into the equation.
When x= -3, y=7,

Thus, the equation of the line is 
I did not even understand that equation
The answer is 10•11, if you look at the pattern, you don't have to solve the addition.
