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

Answer 1

D

Explanation:

eq. of given line is x+y=10

eq. of any line parallel to given line is x+y=a

if it passes through (-1,5) then -1+5=a

or a=4

reqd. eq of line is x+y=4

or y=-x+4
