Find the slope of the line that passes through the points (1,-4) and (3,-1).
Delvig [45]

Answer:

The answer is

\frac{3}{2}  \\

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(1,-4) and (3,-1)

The slope is

m =  \frac{ - 1  -  - 4}{3 - 1}  =  \frac{ - 1 + 4}{2}  =  \frac{3}{2}  \\

We have the final answer as

\frac{3}{2}  \\

Hope this helps you

What is the solution 6x-19= 2(x-1) +11
stiv31 [10]
So because of PEMDAS you want to distribute the 2 to the parentheses so you'll get

6x-19=2x-2+11

Then you can just add like terms

6x-19=2x+9

Now you want to get all your variables on one side so you'd add 19 and subtract 2x

4x=28

Now you divide 28 by 4 

x = 7

La suma de dos numeros es 57, y su diferencia es 9
Korolek [52]

Answer:

La suma de dos numeros es 57.Si el mayor de los dos números es 9 menos que el doble de los más pequeños, encuentre los dos números.

(Scroll Down for Answer!)

Step-by-step explanation:

3*y = 57 + 9 = 66

y = 66/3 = 22

x + 22 = 57

x = 57 - 22 = 35

Por lo tanto, los números son 35 and 22.
