Question

Point U on a graph is located at (4,8), Point V on the same graph is located at (12, 14).

Answer 1

The answer is D hope this helps

Answer 2

Answer:

D

Step-by-step explanation:

gradient is change in y/change in x

gradient of UV = 14-8/12+4=3/4

use equation y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept

use one of the coordinates of U or V, I'll use (4,8)

$y = mx + c$

$8 = \frac{3}{4} (4) + c$

$8 = 3 + c$

c is 5

the equation for UV is

$y = \frac{3}{4} x + 5$

insert each X coordinate given in the question to see if it gives the same y coordinate

when x is 20, y is also 20 so the answer is D
