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
