PLEASE HELP! I know the top part I just need the bottom!

Zolol [24]

slope = (y2-y1)/(x2-x1)

= (70-52)/(8-1)

= 18/7

=2.6

point slope form

y-y1 = m(x-x1)

y-52 = 2.6(x-1)

distribute

y-52 = 2.6x-2.6

add 52 to each side

y = 2.6x+49.4

y = 2.6x +49

the initial temperature is 49.4 or about 49

and it increases about 2.6 degrees each week

Answer:

$- \frac{1}{3}$

Step-by-step explanation:

The only thing important in this question in the original equation is the slope, which is 3, the multiplyer for x. To find the opposite slope follow the steps below.

The first step is to make the original slope into a fraction.

$\frac{3}{1}$

Then flip the numerator and denominator.

$\frac{1}{3}$

Now multiply this value by -1.

$\frac{1}{3} \times ( - 1) = - \frac{1}{3}$

There is the opposite slope of 3.

I have a 74% in my class and I need a 78% to pass what do I need to get on my final exam?

Mkey [24]

So the 74% that you have right now is the other 80% of your grade. So you multiply it by its weight and solve for the other one making it equal to 78%.

(.74)(.8) + (.2)(x) = .78
.592 + (.2)(x) = .78
(.2)(x) = .188
(x) = .94

So, you need to get a 94% on your final test.
