Answer:
y = 2x - 8
Step-by-step explanation:
Note that in the point:
(x , y) = (6 , 4) ∴ (x = 6 , y = 4)
slope = m = 2
The equation of a line is:
y = mx + b
Plug in the corresponding numbers to the corresponding variables:
4 = (2)(6) + b
Simplify. Multiply 2 with 6:
4 = (2 * 6) + b
4 = 12 + b
Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Subtract 12 from both sides:
4 (-12) = 12 (-12) + b
b = 4 - 12
b = -8
Plug in -8 for b:
y = 2x - 8 is your answer.
