Question

Equation A
y = 4 over x + 3

Equation B
y = −2x − 4

Which statement best compares the graphs of the two equations?
both are nonlinear
both are linear
equation a is nonlinear and equation b is linear
equation a is linear and equation b is nonlinear

Answer 1

linear graph looks like this


or

Answer 2

it looks like a decreasing or increasing line.

Answer 3

how do i solve the equations though

Answer 4

you are supposed to graph it.

Answer 5

Plug in points and graph them if you do not know the patterns or behaviors of it.

Answer 6

yeah but how do i plug in something like 4/x +3

Answer 7

plug x=1
the denominator is 4/4=1
so (1,1)

Answer 8

if x gets bigger in the denominator and the numerator is 4, what number is it approaching?

Answer 9

i don't understand haha do i add the 3 to x

Answer 10

\[\frac{ 4 }{ x+3 }\]
that is the equation
as x gets bigger the denominator increases
4/a very large number will equals or approaching 0
In other words 4/x+3 is decreasing slowly because 4/4=1 4/5=0.8 4/6=0.66 that it decreases in a curve, which is not linear.

Answer 11

4/(a very large number)

Answer 12

y=-2x+4
you know what a slope is and which slope value this function has?

Answer 13

i figured it out thanks

Answer 14

No problem!
