What is an equation of the line that passes through the points (-6, -3) and (-3, -5)?

1 answer:

7 0

find the gradient = change in y/change in X

-5 - -3/-3 - -6

= -2/3

take any two point say -3,-5 and equate to the gradient

Y - 5 /X - 3 = -2/3

cross multiply

3y - 15 = -2x + 6

3y = -2x +6 + 15

3y = -2x + 21

y = -2/3x +7

Well area of a triangle is
$\frac{1}{2} b \times h$
so,
$36 \times 2 = 72 \\ 72 \div 9 = 8$
The answer is 8

3a= 3(5) = 15
15 - - 3 = 15+3 = 18
18/6 = 3
b + a = 5 + -3 = -3 + 5 = 2
3 x 2 = 6
