How do we write the approximate slope-intercept for of the equation using points (2,28) and (4,20)?

y = -4x + 36

Step-by-step explanation:

First, find the slope by calculation (y2-y1)/(x2-x1), you should get -8/2, or -4.

Next, plug the points into the equation y-y1 = slope(x-x1), getting y-28 = -4(x-2).

Simplify the equation and you get y =-4x + 36.

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
