Question

find the value of a:

A=(3,4)
B= (a,10)
gradient of AB = 2

Answer 1

Answer:

6

Step-by-step explanation:

The gradient is the slope

slope if a line from (x1,y1) to (x2,y2) is ,

(y2 - y1) / (x2-x1)

applying this we get ...

$2 = \frac{(10 - 4)}{(a - 3)}$

solving this we get ..

a = 6

Have a good day

Answer 2

Answer:

$gradiant( slope)= \frac{y2 - y1}{x2 - x1} \\ \\ 2 = \frac{10 - 4}{a - 3} \\ \\ a = 6$
