Solved by pluggable solver: Find the equation of line going through points
hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (0, 2) and (x2, y2) = (4, 8).
Slope a is .
Intercept is found from equation , or . From that,
intercept b is , or .

y=(1.5)x + (2)

Your graph:





so, , and since , your answer is B.)

m =
(0, 2) &
(4, 8) m = -6/-4 = 3/2
***Using point-slope form,
y-2 = (3/2)(x-0) Using P(0,2)
y = (3/2)x + 2
Ans B
