Write the equation of the line that passes through the points (8, -4) and (-2,5).

Sladkaya [172]

Answer:

The equation in the slope-intercept form will be:

Step-by-step explanation:

Given the points

(8, -4) and (-2, 5)

The slope between two points

$m=\frac{5-\left(-4\right)}{-2-8}$

$m=-\frac{9}{10}$

As the point-slope form is

$y-y_1=m\left(x-x_1\right)$

substituting the values m = -9/10 and (8, -4)

$y-\left(-4\right)=-\frac{9}{10}\left(x-8\right)$

Writing the line equation in the slope-intercept form

$y=mx+b$

where m is the slope and b is the y-intercept

so the equation in the slope-intercept form will be:

$y-\left(-4\right)=-\frac{9}{10}\left(x-8\right)$

$y+4=-\frac{9}{10}\left(x-8\right)$

subtract 4 from both sides

$y+4-4=-\frac{9}{10}\left(x-8\right)-4$

$y=-\frac{9}{10}x+\frac{16}{5}$

Therefore, the equation in the slope-intercept form will be:

$y=-\frac{9}{10}x+\frac{16}{5}$

Mick paid $2.94 in the sale tax on an item that cost $24.00 before tax. At that rate how much would he pay in sale tax for an it

s344n2d4d5 [400]

You could do this with a simple proportion.

24/2.94 = 58/x
x = 2.94 * 58/24
x = 7.11

A railroad track rises 30 feet for every 400 feet of track. What is the measure of the angle of elevation of the track?

gtnhenbr [62]

Answer:

Step-by-step explanation:

Rising 30 feet for every 400 feet of track is not a very large angle of elevation. We set this up as a right triangle to use right triangle trig to solve for the missing angle. The height is 30 and the hypotenuse is 400. The height is the side opposite the angle in question, and the hypotenuse is the hypotenuse! This is the sin ratio. Setting up the ratio using our info:

$sin\theta=\frac{30}{400}$

When you are looking for a missing angle measure, as we are here, use the 2nd-->sin buttons to find the inverse of sin, which looks like this:

$sin^{-1}($

Enter in the fraction 30/400 after the parenthesis and then hit enter to get the angle measure of 4.3 degrees.
