Question

Write the equation of the line that passes through (4, 2) and is parallel to the line y = 2x – 1.
A. x – y = 6
B.
2x – y = 6
C.
2x – y = 1
D.
2x – y = –1

Answer 1

standard form: y=mx + c; where m is slope of the line and c the y-intercept.

so for two parallel lines, their slopes i.e. m is the same. So what is the slope of the new line?

Answer 2

c?

Answer 3

Ah u got the right slope but u also need to find c in the new eqn...try put in x=4 and y=2 to solve for c plz?
