Answer:

<h2>y=<u> -2</u>x+<u>7</u></h2>

<u>Here</u><u>,</u>

Two points given: (3,1) and (7,-7)

slope(m) =  \frac{y2 - y1}{x2 - x1}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{ - 7 - 1}{7 - 3}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{ - 8}{4}  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  - 2 \\

Equation of line is y= Mx+b

y= -2x +b

It passes through (3,1)

1 =  - 2(3) + b \\ 1 =  - 6 + b \\  - b =  - 6 - 1 \\  - b =  - 7 \\ b = 7

Equation of line:

<h3>y= -2x+7</h3>

Hope this helps..

Good luck on your assignment..

Ts temperature as a function of time is given by T(t)=a(1-e^kt)+b
the values of a and b area = 50 Fb = 350 F
this is very evident to equation the b is the initial temperatre of the oven which is 350 F
and also a is the initial temperature of the potato because it is the term multiplied by the exponent term which will indicate the temperature increasse of the potato
