Could someone please help me with this math question

1) 1/2

Step-by-step explanation:

first you must put "y" on its own, so the equation would then look like:

a) 4y = 2x - 18 or b) -4y = -2x + 18,

either or works, then you divide both sides of the equation by the coefficient on y, where on a it is 4 and on b it is -4.

Whatever you get, you would end up with the same answer,

y = 1/2x -18/4,

thus the slope would be 1/2

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.
