Question

What is an equation that passes through -1,2 and is parallel to the point 3x+y=3 ?​

Answer 1

y=3x+5

Explanation:

For this you can use the point-slope formula: y-y1=m(x-x1). Since the line we're looking for is parallel, both slopes are equivalent.

First, you have to rewrite the primary equation into standard form, which would rewrite to y=3-3x or y=-3x+3. Then, you can use the information we have in the point-slope formula:

y-(2)=3(x+1)

y-2=3x+3

y=3x+5

Check:

(2)=3(-1)+5

2=-3+5

2=2
