Answer:

Step-by-step explanation:
the equation to this is

and slop-intercept form is

with m being the slope,
so,

Slope of the line
(3-(-5)) / (-5-(-1))
8 / -4
-2
.30 move the decimal two times to the left.
Answer:
The lines are perpendicular, meaning if they were to intersect, they would form four right angles.
We substitute the given into the equation
given: a=-1, b=2, c=

=(

-1
=

-1
=

-1
=

-1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:

=-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
=


×

(denominator should be -2=common)
=

+

=

which also = to -3.5
