What is the equation of a line that contains the point (4, 0) and is parallel to x + y = 2?
gogolik [260]

Answer:

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

Step-by-step explanation:

0 = -1[4] + b

4 = b

y = -x + 4

If you want it in <em>Standard</em><em> </em><em>Form</em>:

y = -x + 4

+x +x

_________

x + y = 4 >> Line in Standard Form

* Since the <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] is -1 and that parallel lines have SIMILAR SLOPES, -1 remains the same.

I am joyous to assist you anytime.
