Question

What is the equation of the line that is parallel to y=-2x+3 and passes through (4,7)

Answer 1

the answer y=2x-1

Explanation:

since the gradients of equations that are parallel are the same the equation is y=2x + something. we get the something by using substitution.

The 4 is the x and the 7 is the y value.

c will be the something

so it will be 7=2(4)+ C

7=8+C

7-8=c

-1=C
