48. Line h passes through the point (4, 12) and is parallel to line k.
Misha Larkins [42]

Answer:   <em>y = 3/4 x + 8</em>

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

<em>y2 - y1</em>

<em>m = -----------</em>        <em>The slope is 3/4</em>

<em>        </em><em>x2 - x1</em>

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.

<em>y = 3/4x + ?  ----->  12 = 3/4(4) + ?</em>

<em>                               12 = 3 + 8</em>

The y-intercept is 8

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

<em></em>
