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

Hope this was helpful!
