48. Line h passes through the point (4, 12) and is parallel to line k.
Line k passes through the points (-12, -3) and (4,9).
Which of the following is the equation for line h?

48 Line h passes through the point 4 12 and is parallel to line k Line k passes through the points 12 3 and 49 Which of the following is the equation for line h class=

Respuesta :

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
