Question

Does y vary directly as x in this function? y= -3x+4

Answer 1

Y = kx - y varies directly as x in this function
 - y varies inversely as x in this function

For  y varies directly as x
For  y varies inversely as x

Answer 2

Yes, y varies directly as x in this function, for the outcome of y is depended on what x is

for example:

when x = 10, y will = -24

y = -3(10) + 4
y = -30 + 4
y = -24

when x = -10, y will = 34

y = -3(-10) + 4
y = 30 + 4
y = 34


hope this helps
