The equation of the linear line has a general form: y=mx+c where m is the slope = 2 c is the y-intercept So, the equation of the line now has the form: y=2x+c We are given that (4,5) belong to this line, so, we will use this point and substitute in the equation to get the value of c as follows: y=2x+c 5=2(4)+c 5=8+c c = 5-8=-3
Based in the above, the equation of the line is: y = 2x - 3
