Wrote the equation of the line that passes through (3,4) and (2,-1) in slope intercept form

nordsb [41]

So the equation of a line is y=mx + b.

In order to find the slope given only two coordinates we have to use a formula to find slope. It is:
y2-y1/x2-x1.

So let’s get all the values first from (3,4) and (2,-1).

y2= -1
y1=4
x2=2
x1=3
Plug in the values now.
-1 - 4 = -5
-5/2-3=5

The slope is 5x.

Now let’s find the y intercept, to find the y intercept, we have to do a formula which is:
y-y1=m(x-x1)
So let’s plug in the values.
y-4=5(x-3)
y-4=5x-15
+4 +4
y=5x-11

The final answer is y=5x-11!!!

2. Craig read 3 books each week for 3 weeks. Joe read 4 books a week for 3 weeks. How many more books did Joe read? Choose the a

Burka [1]

Answer:

4*3 - 3*3;

Joe read 3 more books than Craig

Step-by-step explanation:

Given

Craig:

3 books weekly for 3 weeks

Joe:

4 books weekly for 4 weeks

Required

How many more books did Joe read.

First, we need to determine number of books Craig reads

If in a week, Craig reads 3 books

Then in 3 weeks, Craig reads 3 * 3 books

Next, we need to determine number of books Joe reads

If in a week, Joe reads 3 books

Then in 4 weeks, Joe reads 4 * 3 books

Next, we determine the difference;

$Difference = 4 * 3 - 3 * 3$

$Difference = 12 - 9$

$Difference = 3$

Hence, Joe reads 3 more books

Option D answers the question.
