What is the equation of the line that is parallel to the graph of y = 2x - 5 and passes through the point (4,2)?

mezya [45]

Answer:

$y=2x-6$

Step-by-step explanation:

A line parallel to another will have the same gradient
So the equation will be $y=2x+c$
We need to find out what c is, so substitute in the values for x and y
$2=2\times 4 + c$
$2=8+c$
$c=2-8=-6$
So your equation is $y=2x-6$ !
