I dont know how to find parallel

Hi, Haley.

Parallel lines have the same slope. So let's write the first equation in slope-intercept form:

4x + 2y = 8

2y = -4x + 8

y = -2x + 4

The slope is -2. To find the other line, use -2 for the slope and substitute (-1,5) in for x and y into the point-slope formula:

**y - y _{1} = m( x - x_{1})**

y - 5 = -2(x + 1)

y - 5 = -2x - 2

y = -2x + 3

Hope this helps!

y=-2x+4 hence the slope of all lines in the plane parallel to it must have a slope =-2.the equation of the line through (-1,5) is y-5=-2(x+1) which can be written as y=-2x+3
