Find the slope of a line given the following two points: (4, 3) and (5, 2). 1 -1 2 -2

1 answer:

7 0

Given two points; (x₁,y₁) and (x₂,y₂) the slope is:

m=(y₁-y₂) / (x₁-x₂) or m=(y₂-y₁) / (x₂-x₁)

In this case:
(4,3)
(5,2)

m=(5-4)/(2-3)=1/-1=-1

Answer: the slope is -1

Write an equation of the line that passes through the given points (7,9),m =4

Alla [95]

Answer:

$y = 4x - 19$

You should also try solving it yourself to make sure I did not make any mistake.

Step-by-step explanation:

We already know the slope so, so far the equation should look like this.

$y = 4x + b$

Now we just need to insert the point into the equation. So point (7,9) 7 should replace the x and 9 will replace the y. It will look like this:

$9 = 4 \times 7 + b$

when you solve this equation you'll get b

$b = - 19$

So the equation is

$y = 4x - 19$
