In order to answer this question, I'll have to get that equation
in standard form ===> y = mx + b .
14x + 4y = 24
Subtract 14x from each side: 4y = -14x + 24
Divide each side by 4 : y = -3.5x + 6
There's the standard form we need ==> y = -3.5x + 6
That -3.5 is our slope.
That 6 is our y-intercept.
Do you have a picture so that ik what the track looks like
Answer:
the answer is the C
Step-by-step explanation:
Answer:
a) y does NOT vary directly with x
b) y = 2.5x -6.5
Step-by-step explanation:
If variation were direct the ratios of y to x would be constant. They are not:
6/5 ≠ 11/7
y does not vary directly with x.

y changes by 5 from 6 to 11 when x changes by 2 from 5 to 7. Then the slope of the linear function rule is (change in y)/(change in x) = 5/2. Using a point-slope form of the equation of a line, we can write the rule as ...
y = m(x -h) +k . . . . . . . . for a line of slope m through point (h, k)
y = (5/2)(x -5) +6
y = 2.5x -6.5 . . . . . simplify
