Equation: y=3x -2
6-2= 4
16-4=12
12/4=3
Plug the one of the coordinates into the equation y=mx+b.
4=3(2)+b
4=6+b
-6 -6
-2=b
Hopefully I explained it well... :)
Answer:
Step-by-step explanation:
(2,4) and (6,16)
y2 = 16, y1 = 4, x2 = 6 and x1 = 2
Slope m = {y2 - y1}/{x2 - x1}
m = {16 - 4}/{6 - 2}
m = 12/4
m = 3
The equation of line
y - y1 = m(x - x1)
y - 4 = 3(x - 2)
y - 4 = 3x - 6
y = 3x - 6 + 4
y = 3x - 2
