Write the equation of the line to n slope intercept from (3,5) and (-3,-1)

Answers

Answer:

The equation of your line is y=1x+2

Step-by-step explanation:

first you take y2-y1/x2-x1

y2=-1     y1=5

x2= -3   x1= 3

that gives you your slope so (-1-5)/ (-3-3) = 1

y=mx+b

mx is your slope

y=1x+b

to solve for b you input your slope and one of your points (I used (3,5)

5=1(3) +b

solve for b and you get 2

then put your mx and b into the equation of a line

y=1x+2

and thats your answer

You can also check your work by using a graphing calculator and checking that the line goes through those two points.

Step-by-step explanation:

When a line is parallel to another line it means that they will never meet. This requires the slope to be the same, so no matter the line, if it is parallel to a line with a slope of -7, then its slope is also -7.

Answer: (-25)/(2)

Steps:  x | 0 | 2 | 4 | 6 | 8 |

          "x" has a constant rate change of +2

          y | 100 | 75 | 50 | 25 | 0 |

          "y" has a constant rate change of -25  

         

          therefore,  y/x = -25/2
