What is an equation of the line that contains the point (3 -1) and is perpendicular to the line whose equation is y=-3x+2?
Svetach [21]
The slope of a perpendicular line is the opposite reciprocal of the original slope. So the slope is 1/3.
Answer: y = x/3 - 2

Help with math please asap <br> 1. Solve the inequality <br> 1/5 + 1/3 X &gt; 1/2 X - 1/4
Finger [1]

Answer:

The solution set is x < 2.7

Step-by-step explanation:

To start, get all of the x terms on the right side and all the constant terms on the left.

1/5 + 1/3x > 1/2x - 1/4

1/5 + 1/4 + 1/3x > 1/2x

1/5 + 1/4 > 1/2x - 1/3x

Now give the terms on each side common denominators.

4/20 + 5/20 > 3/6x - 2/6x

9/20 > 1/6x

Now we can multiply both sides by 6.

27/10 > x

2.7 > x

What is an equation of the line that passes through the points (6, 0) and (-1, -7)?
Orlov [11]

Answer:

y = x - 6

Step-by-step explanation:

We want to write a line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

First, we need to find the slope, which is just the change in the y-coordinates divided by the change in the x-coordinates:

slope = m = \frac{6-(-1)}{0-(-7)} =\frac{7}{7}=1

Our equation now looks like this: y = x + b

Now, to find the y-intercept, let's use one of the points provided and plug those values of x and y into the incomplete equation we have to solve for b:

0 = 6 + b  ⇒  b = -6

So, the equation is: y = x - 6.

Hope this helps!
