Question

Please help me with 10c.

Answer 1

Answer:

18

Step-by-step explanation:

for x intercept y = mx + b you need to make y = 0

line passes through ( 3 , -4 )  and slope is 2/3

now substituting the values in it we get  

-4 = (2/3)(3) + b

==> b = -6

now line equation

y - y1 = m ( x - x1 ) + b

y- ( - 4 ) = ( 2/3 ) (x - 3) + (-6)

x intercept so y = 0

0 + 4  =  (2/3) (x-3) -6

(2/3)(x-3) = 10

x - 3 = 15

x = 18
