Which equation has the greatest rate of change? y=12x-7
y=5x+9

y=4x+12

y=X+36

y=12x-7

Step-by-step explanation:

Rate of change is the same thing as slope which can be found by looking at the value before the x. Since 12 is the largest number, it has the largest rate of change.

It is y=0.6x-3.2

Step-by-step explanation:

A line parallel to y = 0.6x + 3 will be of the form:

y = 0.6x + k

where k is a constant.  It passes through (-3,-5)

That being so,

y = 0.6x + k

-5 = 0.6 * (-3) + k

-5 = -1.8 + k

k = -5 + 1

k= -3.2

Therefore the answer is y = 0.6x - 3.2.
