Point-slope equation of the line through (6,4) and (7,2)
Nataly [62]

Answer:

<h2>y - 4 = -2(x - 6) or y - 2 = -2(x - 7)</h2>

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (6, 4) and (7, 2). Substitute:

m=\dfrac{2-4}{7-6}=\dfrac{-2}{1}=-2

Using the first point

y-4=-2(x-6)

Using the second point

y-2=-2(x-7)

kow [346]

Answer:

56 quizzes

Step-by-step explanation:

40 quizzes = 5 weeks

To find the unit rate of quizzes / week, we can divide both sides by 5

40/5 quizzes = 5/5 weeks

8 quizzes = 1 week

Multiply both sides by 7 to find the amount of quizzes in 7 weeks

8 * 7 quizzes = 1 * 7 weeks

56 quizzes = 7 weeks
