This is a proportion. To solve a proportion, cross multiply

K x 5 = 5k

2 x 9 = 18

5k = 18

Perform the opposite operation to isolate k by dividing both sides of the equation by 5

$k= \frac{18}{5}$

A line is defined by the equation y=2/3x-6. The line passes through a point whose y-coordinate is 0. What is the x-coordinate of

adelina 88 [10]

Y = (2/3).x - 6. If y=0, then 0= (2/3).x - 6. Solve for x:

2x/3 - 6 = 0
Same denominator:
(2x - 18)/3 = 0
2x - 18 = 0
2x = 18 and x = 9 (x-coordinate)
