Answer:

(A) $\boxed{\bold{y=\frac{3}{7}x+\frac{2}{7}}}$

(B) $\boxed{\bold{2 \ = \ \frac{3}{7} * \ 4 \ + \ \frac{2}{7} }}$

Explanation:

(A) Slope: y = mx + b

m = 3/7

b = 2/7

Slope = $\bold{\frac{y_2-y_1}{x_2-x_1}}$

$\bold{\left(x_1,\:y_1\right)=\left(-3,\:-1\right),\:\left(x_2,\:y_2\right)=\left(4,\:2\right)}$

M = $\bold{\frac{2-\left(-1\right)}{4-\left(-3\right)}: \ \frac{3}{7} }$

Y intercept

$\bold{y=\frac{3}{7}x+b}$

Plug in $\bold{\left(-3,\:-1\right)\mathrm{:\:}\quad \:x=-3,\:y=-1}$

$\bold{-1=\frac{3}{7}\left(-3\right)+b}$

Isolate B

$\bold{-1=\frac{3}{7}\left(-3\right)+b}$

b = $\bold{\frac{2}{7} }$

(B) 4 = x, 2 = y

2 = 3/7 * 4 + 2/7

The interval where the function is nonlinear and decreasing is 0 < x < 4

<h3>How to determine the interval where the function is nonlinear and decreasing?</h3>

The straight lines on the graph are the intervals where the graph is linear

This means that the straight lines on the graph will not be considered

Considering the curve, the graph decrease from x = 0 to x = 4

This can be rewritten as:

0 < x < 4

Hence, the interval where the function is nonlinear and decreasing is 0 < x < 4

Describe a real world situation that can be modeled by 5t

jeka57 [31]

I used to shovel snow for $5 an hour.

If ' t ' was the number of hours I spent shoveling somebody's driveway,
then ' 5t ' was the number of dollars he owed me for the job.

' t ' didn't even have to be a whole number. It worked fine with any number.
