3 plants/seed packet

Step-by-step explanation: Using rise/run, from the y-int, the rise is 30 and the run 10, or 30/10 which = 3.

Step-by-step explanation:

We can find the rate of change by picking any two points on the line in the form (x, y) and using the equation below to find the slope (m):

To make things easier, let's pick two points which offer us whole numbers. So: (20, 90) and (0, 30) seem perfect. Plug it into the formula:

Thus, the rate of change of the given line is 3.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

the distance between the school and her home is 3.6km.

12 mins = 0.2 hours = 1/5 hour

54 ÷ 3 = 18km per hour

1/5 of 18 = 3.6km per 12 mins
