Write the equation of the line in fully simplified slope-intercept form.

Aneli [31]

Answer:

$y = -\frac{1}{5}x -1$

Step-by-step explanation:

Given

The attached graph

Required

Determine the line equation

First, list out two points from the graph

$(x_1,y_1) = (-5,0)$

$(x_2,y_2) = (0,-1)$

Next, calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{-1-0}{0 -(-5)}$

$m = \frac{-1}{0 +5}$

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

The equation in slope intercept form is:

$y = m(x - x_1) + y_1$

This gives:

$y = -\frac{1}{5}(x - (-5)) + 0$

$y = -\frac{1}{5}(x +5)$

Open bracket

$y = -\frac{1}{5}x -1$

Ryan drove 480 miles and used 20 gallons of gas. How many miles did Ryan's car get per gallon? Write an equation that would solv

lisabon 2012 [21]

Answer:

24 miles per gallon

Step-by-step explanation:

Step one:

given data

total distance covered= 480miles

The total amount of gallons used is = 20

The miles per gallon

= 480/20

=24 miles per gallon

Step two:

hence the equation that we used in solving the problem is stated as

miles per gallon= total distance/total gallon sused

What is the slope of the line 4x + 7y = - 35?

sasho [114]

Answer:

-4x/7

Step-by-step explanation:

4x + 7y = -35

7y = -4x - 35

y= -4x/7 - 35/7

y= -4x/7 - 5

-4/7 (the slope is the x equation)

Inverse Functions. An inverse function goes the other way! Let us start with an example: Here we have the function f(x) = 2x+3, written as a flow diagram: The Inverse Function goes the other way: So the inverse of: 2x+3 is: (y-3)/2 .
