You can put this solution on YOUR website! find the y-intercept of the line with the slope of 2 and through the point of (14,3)... I know the answer is 8 but I do not know how to solve this problem
**
Equation of a line: y=mx+b, m=slope, b=y-intercept
y=2x+b
solving for b using coordinates of given point on line (14,3)
3=2*14+b
b=-28+3=-25
For answer to be 8, coordinates of given point should be (3,14) instead of (14,3)
14=2*3+b
b=14-6=8
