The slope of the line that contains the points (1, -1) and (2, 3) is 4. What is the y-intercept?

Answers

y- intercept =-5
y-y1=m(x-x1)
y-(-1)=4(x-1)
y+1=4(x-1)
y+1=4x-4
y=4x-4-1
y=4x-5
Or
y=4x+b
-1=4(1)+b
-1=4+b
-1-4=b
-5=b. Y-intercept is -5

The y-intercept of the line is -5.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

We can use the slope-intercept form of a linear equation to find the

the y-intercept of the line.

The slope-intercept form of a linear equation is:

y = mx + b

where m is the slope of the line, and b is the y-intercept.

We are given the slope of the line that contains the points (1, -1) and

(2, 3) is 4.

Therefore, we can substitute m = 4 and one of the points into the equation, and solve for b.

Let's use the point (1, -1):

y = mx + b

-1 = 4(1) + b

-1 = 4 + b

b = -1 - 4

b = -5

The y-intercept of the line is -5.

The equation of the line in slope-intercept form is:

y = 4x - 5

Thus,

The y-intercept of the line is -5.

A 12-pound bag weighs more than a 200-ounce bag. True or false?
Question 9 options:
True
False

Answers

Answer:

False. A 200-ounce bag would weigh more than a 12-pound bag.

Hope this helps!

The statement "A 12-pound bag weighs more than a 200-ounce bag." is True.

What is Unit Conversion?

The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

Given:

A 12-pound bag weighs more than a 200-ounce bag.

As, we know

1 pound = 16 ounce

So, the weight of bag in ounces

=12 pound

= 12 x 16

= 192 ounce

So, the statement is True.

A. $1.58
B. $1.44
C. $1.30
D. $1.17

Answers

Answer:

C. $1.30

Step-by-step explanation:

Multiply 0.79 and 0.65 (65%) which is about 0.51.

Add that to 0.79.

Answer:

$ 1.30

Step-by-step explanation:

Increased price =  65% of $0.79

                          [tex]\frac{65}{100}*0.79[/tex]

                         = 0.65 * 0.79

                        = 0.5135

                         = $ 0.51

Selling price  = 0.79 + 0.51 = $ 1. 30
