Question

eva draws a line that includes the points (2,0) and (-2,2). Which function gives all the points (x,y) on this line?

Answer 1

Answer:

Slope of the line

$m = \frac{2 - 0}{ - 2 - 2} = \frac{2}{ - 4} = - \frac{1}{2}$

Equation of line

$\frac{y - 0}{x - 2} = - \frac{1}{2} \\ 2y = - x + 2 \\ x + 2y = 2$
