Answer:
(x) =
Step-by-step explanation:
let y = f(x), then rearrange making x the subject
y = x + 4 ( subtract 4 from both sides )
y - 4 = x ( multiply both sides by 5 to clear the fraction )
5y - 20 = x
Change y back into terms of x with x = (x) , then
(x) = 5x - 20
Answer:
Option (4)
Step-by-step explanation:
Slope a line passing through two points and
is given by,
m =
Since, blue line is passing through two points (-4, -2) and (0, 4),
Slope of the blue line =
=
Similarly, green line is passing through two points (-4, 1) and (0, -2),
Slope of the green line =
=
Since,
Neither these slopes are opposite reciprocals.
Therefore, both the lines are neither parallel nor perpendicular.
Option (4) will be the correct option.
