Question

Find an equation of the line l that contains the points left parenthesis 0 comma 0 right parenthesis(0,0) and left parenthesis 4 comma 1 right parenthesis .

Answer 1

the actual answer is 4x-1

Explanation:

Answer 2

(0,0) and (4,1)
Find the slope: m = (y2-y1)/(x2-x1) = (1-0)/(4-0) = 1/4
Input m, x1, and y1 into the Point-Slope equation:
y - y1 = m(x - x1)
y - 0 = 1/4 (x - 0)
y = 1/4 x
