Answer:

Step-by-step explanation:
Let the equation of the perpendicular line is,
y = mx + b
where m = slope of the line
b = y-intercept
From the graph, slope of the line passing through (0, -1) and (3, 1),
m' =
m' = 
m' = 
To get the slope (m) of this line we will use the property of perpendicular lines,
m × m' = (-1)
m ×
= -1
m = 
Equation of the perpendicular line will be,

x-intercept of the line is (-3) therefore, point on the line is (-3, 0)
0 = 
b = 
Equation of the line will be,

Answer:

Step-by-step explanation:
We are asked to find the equation of a line given a point and the slope. We will use the point-slope formula.

In this formula, m is the slope and (x₁, y₁) is the point the line passes through. The slope of this line is -4 and the line passes through (-2,5).
Substitute the values into the formula.


We are finding the equation of the line, so we should find the slope-intercept form or y=mx+b ( where m is the slope and b is the y-intercept).We must isolate the variable y on one side of the equation.
First, distribute the -4 on the right side of the equation. Multiply each term inside the parentheses by -4.


5 is being subtracted from y. The inverse operation of subtraction is addition, so we will add 5 to both sides of the equation.


The equation of the line is y= -4x -3. The slope of the line is -4 and the y-intercept is -3.
The answer is 4.25
In the first step he never distributed the 1/12 to the 18. He only distributed to the 14
Answer:
$5.66/gal
Step-by-step explanation:
To calculate the current price of gas, multiply $4.35/gal by (1 + 0.30), or by 1.30:
1.30($4.35/gal) = $5.66/gal
Answer:
360
Step-by-step explanation:
24 divided by 6 = 4 which means each foot = 4 foot shadow
90 x 4 =360
