Question

Equation of the line that passes through the points given (0,2) and (-2,0)

Answer 1

The slope of the line is change in y over change in x. In this case, we have 0-2/-2-0 this gives us -2/-2 which is 1
So we have y =x + c where c is the y value at the y intercept (in this case 2)
So your equation is y = x + 2
