Answer:   y = 3/4 x + 8

Step-by-step explanation: First  you must find the slope of line k.

y2 - y1

m = -----------        The slope is 3/4

       x2 - x1

Since the two lines are paralell you know that line h has the same slope.

Next you must find the y-intercept by replacing x and y with the values given by the point.

y = 3/4x + ?  ----->  12 = 3/4(4) + ?

                              12 = 3 + 8

The y-intercept is 8

Your equation for line h is y = 3/4 x +8
