Question

What is the equation of the line described below written in slope-intercept form?

the line passing through point (-1, 5) and parallel to the line whose equation is x + y = 10


y = x - 4
y = x + 4
y = -x + 4

c

Answer 1

y = -x + 10

The slope of that expression is -1.

Hence, by point-slope form, noting that parallel lines must have the slopes of -1 [same slopes], and that the point for the new line is (-1,5)...

y - 5 = -(x + 1)
y - 5 = -x - 1
y = -x + 4
