What is the slope of a line with rise down 3 and runleft 5?

Sagot :

we know that

The slope is equal to divide rise by run

so

Let

m the slope

m=rise/run

we have

rise=-3 ------> negative because is down

run=-5 -----> negative because is left

substitute

m=-3/-5

m=0.6 positive

Part 2

slope=2/4=0.5

slope positive

up is positive/ dow is negative

right is positive/ left negative

Part 3

we have

y=-3x+5

this is the equation of a line in slope intercept form

so

y=mx+b

where

m is the slope

b is the y-intercept'

so

m=-3

b=5

the slope is -3

Part 3

we have

4x+2y=-4

the equation of the line in slope intercept form is equal to y=mx+b

isolate the variable y in the given problem

so

2y=-4-4x

divide by 2 both sides

y=-2-2x

y=-2x-2

Part 4

5x-4=11

solve for x

5x=11+4

5x=15

x=3

the solution is x=3
