$\frac{5}{3} + \frac{2}{3} = \frac{7}{3}$
Because the denominators are same, you can just add the numerators.

Use the slope formula to find the slope of the line through the points (-2, 2) and (-7, -6).

shtirl [24]

Answer:

8/5

Step-by-step explanation:

Slope is calculated by the change in y over the change in x. The change in y values is -8 and the change in x values is -5. The negatives cancel out to get 8/5.

A TRAFFIC LIGHT IS RED FOR 38 SECONDS YELLOW FOR 10 SECONDS AND GREEN FOR ONE MINUTE AND TWELVE SEONDS. IN A CONSTANTLY REPEATIN

morpeh [17]

The chance is 3/5 that the light will be green.

Added together the total seconds for the traffic light to complete the cycle is 120 (38+72 (1 min and 12 sec) +10.

And the green light proportion is: 72/120

We simplify by dividing by 12, which is a factor and we get: 6/10 that simplifies to 3/5.

Hope this helps!

Write the equation in slope intercept form that passes through (-5,10) and (2,4)

balu736 [363]

Answer:

$\displaystyle y = -\frac{6}{7}x + 5\frac{5}{7}$

Step-by-step explanation:

First, find the rate of change [slope]:

$\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-10 + 4}{5 + 2} = -\frac{6}{7}$

Now plug these coordinates into the Slope-Intercept Formula. It does not matter which ordered pair you choose:

4 = −6⁄7[2] + b

−1 5⁄7

$\displaystyle 5\frac{5}{7} = b \\ \\ y = -\frac{6}{7}x + 5\frac{5}{7}$

_______________________________________________

10 = −6⁄7[−5] + b

4 2⁄7

$\displaystyle 5\frac{5}{7} = b \\ \\ y = -\frac{6}{7}x + 5\frac{5}{7}$

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

I am joyous to assist you anytime.
