The point-slope form:

m - slope
x₁, y₁ - the coordinates of a point
It passes through the points (1,-2) and (2,2).

I could be 7- or it could be just 7
A quadratic expression<span> is any mathematical </span>expression<span> whose power or degree is two. In other words, any </span>expression<span> that uses variables where the highest exponent or the </span>expression's<span> degree is two is a </span>quadratic expression<span>. The </span>expression<span> must have a power of two, no higher nor lower.</span>
Endpoint T would be at the coordinates (4, -11)
