Question

Write the equation of the line that passes through (3, 6) and (0, –3) in slope-intercept form.

y = 3x – 6

y = 3x – 3

y = 3x + 3

y = 3x + 6

Answer 1

gradient = (6-(-3))/(3-0) = 9/3 = 3 so it has to be 3x. Intercept happens at x=0 and they tell you one point is (0,-3) which is when x=0 therefore y= -3 which is intercept. So equation is y=3x -3

Answer 2

y=3x-3

Answer 3

y=mx+b
where m is slop
m=(y2-y1)/(x2-x1)
m=3
y=3x+b
(3,6)
6=3(3)+b
b=-3
then
y=3x-3
