I say the answer is C 2*X=8 8+4=12

The answer is b because y=3x y=12 and  x=4 so 3x4 = 12 which is wat b shows

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
