Answer is 3/72

multiply the denominator and numerator of 3/8 by 9 (27/72)
multiply the denominator and numerator of 3/9 by 8 (24/72)

this is to get the same denominator of 72

then just subtract 
27/72 - 24/72 = 3/72

Answer:
The result is 1/24

Explanation:
First step is to get the common denominator:
The common denominator here will be 8*9 = 72
Therefore:
3/8 = 27/72
3/9 = 24/72

Second step is to do the subtraction:
27/72 - 24/72 = (27-24) / 72 = 3/72

The last step is to simplify the result:
3/72 = 1/24

Hope this helps :)

Find the equation of the line passing through (1,4) and (-2,-1).
wel

Answer:

y=5/3x+7/3

Step-by-step explanation:

Here are the points: (1,4) and (-2, -1)

let's first find the slope, which is with the equation m=(y2-y1)/(x2-x1) (m is the slope)

label the points:

x1=1

y1=4

x2=-2

y2=-1

now subsitute into the equation

m=(-1-4)/(-2-1)

m=-5/-3

m=5/3

the slope of the line 5/3

Here's the equation so far:

y=5/3x+b (b is a place holder)

we can substitute either one of the points into the equation so far to find b, because the line will pass through both of them>

let's use (1,4) as an example

4=5/3(1)+b

4=5/3+b

subtract 5/3 from both sides

7/3=b

Now, put it all together:

y=5/3x+7/3

Hope this helps!

This if for my study guide and I'm so confused, can someone help me with this one?
user100 [1]

Answer:

The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a.

The slope-intercept form of the equation of a line is a useful form for graphing as well as for understanding the relationship between x and y. In this lesson, learn how the slope-intercept form helps you understand the equation of a line.

The equation of a line can be written many different ways, and each of these ways is valid. The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.

A line is a relationship between two things - but not just any relationship. When you have a linear relationship, one that can be graphed as a line, there is one big condition:

No matter how much you have of a thing (often called x), if you add one more you always get a consistent amount more of the other thing (often called y).
