What is the equation of the line that passes through the points (6,8) and (-3,2)

Vikki [24]

The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (6, 8) and (-3, 2). Substitute:

$m=\dfrac{2-8}{-3-6}=\dfrac{-6}{-9}=\dfrac{2}{3}\\\\y-8=\dfrac{2}{3}(x-6)\qquad|\text{use distributive property}\\\\y-8=\dfrac{2}{3}x-4\qquad|+8\\\\y=\dfrac{2}{3}x+4\qquad|-\dfrac{2}{3}x\\\\-\dfrac{2}{3}x+y=4\qquad|\cdot(-3)\\\\2x-3y=-12$

Answer:

point-slope form: $y-8=\dfrac{2}{3}(x-6)$

slope-intercept form: $y=\dfrac{2}{3}x+4$

standard form: $2x-3y=-12$

Darcy harvest 8 3/4 acres of corn every 5/6 of an hour. How many acres per hour?

otez555 [7]

Answer:

The answer is $10\frac{1}{2}\ per\ hour.$

Step-by-step explanation:

Given:

Darcy harvest 8 3/4 acres of corn every 5/6 of an hour.

Now, to find the acres per hour it takes to harvest.

Darcy harvest = $8\frac{3}{4}=\frac{35}{4}\ acres.$

The time he took to harvest = $\frac{5}{6}\ hour.$

So, to get the acres per hour we put formula:

$Distance = \frac{35}{4}\ acres.$

$Time=\frac{5}{6}\ hour.$

$Speed=\frac{distance}{time}$

$Speed=\frac{\frac{35}{4}}{\frac{5}{6}}$

$Speed=\frac{35}{4}\times \frac{6}{5}$

$Speed=\frac{210}{20}$

$Speed=\frac{21}{2}$

$Speed=10\frac{1}{2}\ per\ hour.$

Therefore, the answer is $10\frac{1}{2}\ per\ hour.$
