Use the slope formula
$\frac{ - 6 - ( - 5)}{ - 7 - ( - 2)} \\ \frac{ - 6 + 7}{ - 7 + 2} \\ \frac{1}{ - 5}$

In Exercises 26-28, write an equation. Then solve.

saul85 [17]

Answer:

The temperature outside is 75.6°F

Step-by-step explanation:

We are given the following in the question:

The temperature of dry ice = - 109.3°F

Let x be the temperature outside in Fahrenheit.

It is given that the temperature of dry ice is 184.9°F less than the outside temperature.

Thus, we can write the equation:

$x - 184.9 = -109.3$

Solving, the above equation, we get:

$x - 184.9 = -109.3\\x = -109.3 + 184.9\\x = 75.6$

Thus, the temperature outside is 75.6°F

Helena wrote the equation using point-slope form for the line that passes through the points (5, 1) and (3, 5). Analyze the step

viva [34]

Answer:

In step 2, she didn’t use an x and y from the same coordinate pair

Step-by-step explanation:

see the attached figure to better understand the problem

we have the points (5, 1) and (3, 5)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute

$m=\frac{5-1}{3-5}$

$m=\frac{4}{-2}$

$m=-2$

step 2

The equation of the line in point slope form is

$y-y1=m(x-x1)$

take the point (3,5)

$m=-2$

substitute

$y-5=-2(x-3)$

$y-5=-2x+6$

$y=-2x+6+5$

step 3

$y=-2x+11$

therefore

In step 2, she didn’t use an x and y from the same coordinate pair
