# Point-slope equation of the line through (6,4) and (7,2)

Answer from: 36murrayjonte

y - 4 = -2(x - 6) or y - 2 = -2(x - 7)

Step-by-step explanation:

The point-slope form of an equation of a line:

m - slope

The formula of a slope:

We have the points (6, 4) and (7, 2). Substitute:

Using the first point

Using the second point

Answer from: djfluffyman999

-2

Step-by-step explanation:

You should use the formula Y2-Y1/X2-X1.

2-4/7-6

Answer from: orangeicecream

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

To calculate m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (6, 4) and (x₂, y₂ ) = (7, 2)

m = = = - 2

There are 2 possible point- slope equations

Using (a, b) = (6, 4), then

y - 4 = - 2(x - 6)

OR

Using (a, b) = (7, 2), then

y - 2 = - 2(x - 7)

For this option, you will work individually. the pythagorean theorem can be used in many real-world scenarios. part 1 write your own real-world scenario where the pythagorean theorem can be applied to find a missing piece. you may choose to write a problem that is two- or three-dimensional in nature. be sure that you will be able to draw a diagram of your scenario. write out your problem and submit it for part 1. be sure to end your scenario with a question. part 2 draw a diagram of the scenario you created in part 1. you may draw by hand and scan and upload your drawing or create a computer-generated drawing for submission. be sure to label all parts and dimensions of the drawing. part 3 solve the question that you posed in part 1. show all of your steps in answering the question. for this option, you will need to submit all three parts for full credit—your real-world problem and question, the diagram that you created, and your work solving the problem, showing all steps. * note that your instructor is looking for your own original idea. while it is acceptable to use the internet for research and inspiration, academic integrity policies apply.
