The slope-intercept form of the equation of a line that passes through point (–3, 8) is y = –x + 6. What is the point-slope form
Alex

The other format for straight-line equations is called the "point-slope" form. For this one, they give you a point <span>(x1, y1)</span><span> and a slope </span>m, and have you plug it into this formula:

<span><span>y </span>–<span> y</span>1<span> = m</span>(<span>x </span>–<span> x</span>1)</span>

Don't let the subscripts scare you. They are just intended to indicate the point they give you. You have the generic "x" and generic "y<span>" that are always in your equation, and then you have the specific </span>x<span> and </span>y<span> from the point they gave you; the specific </span>x<span> and </span>y<span> are what is subscripted in the formula. Here's how you use the point-slope formula:</span>

<span><span>Find the equation of the straight line that has slope </span><span>m = 4</span><span> and passes through
the point </span>(–1, –6).</span><span><span>This is the same line that I found on the </span>previous page<span>, so I already know what the answer is (namely, </span><span>y = 4x – 2</span>). But let's see how the process works with the point-slope formula.<span>They've given me </span><span>m = 4, x1 = –1,</span><span> and </span><span>y1 = –6</span>.  I'll plug these values into the point-slope form, and solve for "<span>y=</span>":<span><span><span>y </span>–<span> y</span>1 = m(<span>x </span>–<span> x</span>1)
y – (–6) = (4)(x – (–1))
y + 6 = 4(x + 1)
y + 6 = 4x + 4
y = 4x + 4 – 6</span><span>y = 4x – 2</span> Copyright © Elizabeth Stapel 2000-2011 All Rights Reserved</span></span>

This matches the result I got when I plugged into the slope-intercept form. This shows that it really doesn't matter which method you use (unless the text or teacher specifies). You can get the same answer either way, so use whichever method works more comfortably for you.

<span>You can use the Mathway widget below to practice finding a line equation using the point-slope formula. Try the entered exercise, or type in your own exercise. Then click "Answer" to compare your answer to Mathway's. (Or skip the widget and continue with the lesson.)</span>

1+4=5; 2+5=12; 3+6=21; 8+11=?
dybincka [34]
The pattern:
So it goes, 1, 2, 3, as the first number in each equation right.
Then it goes 4,5,6 as the second number in each equation.
<span>In other words, the first number + 3 = the second number
</span>
The sum or 3rd number is a zig zag pattern from the first and second numbers as shown below.
1 2 3 4 5 6   <span>7  </span>8   9 
4 <span>5 </span>6 7 8 9 10 11 <span>12
</span>
1 * 5 = 5, 2 * 6 = 12, 3 * 7 = 21 .... 8 * 12 = 96

<span>So the answer of </span><span>8+11=96</span>

Please give me an equation for this situation
asambeis [7]

Answer:

y=8.50x    

Where y is the total cost and x is the number of cars washed

Step-by-step explanation:

Divide 93.50 by 11 and you get 8.50. When you divide 195.50 by 23, you still get 8.50. Therefore, the cost of the car wash is 8.50 per car.

Student work<br> TRY IT #1<br> Write each of the following as a rational number.<br> b. 3<br> c-4
tino4ka555 [31]

Answer:

  b.  3 = 3/1

  c.  -4 = -4/1

Step-by-step explanation:

An integer can be written as a rational number with a denominator of 1. The denominator can be anything else, too, in which case the numerator must be multiplied by that same value.

__

b. 3 = 3/1 = 6/2 = 27/9

__

c. -4 = -4/1 = 8/-2 = -12/3
