    to find the slope \(\dfrac{16-4}{5-3}=\dfrac{12}{2}=6\)

    right now your equation is \(y=6x+b\)

    b is the y-intercept which we are going to find

    put the ordered pair 3,4 into the equation \(4=6*3+b\\6*3=18\\4-18=-14\\-14=b\)

    so the slope is 6 and the y-int is -14 put that all together and you get \(y=6x-14\)
