Answer:
Step-by-step explanation:
i'm not sure if you're trying to find the equation of the line ?? but i'll assume that's the case and find the slope-intercept form equation of the line.
slope intercept form is , where
is the slope and
is the y-intercept. since the slope is already identified, you can plug in
for
.
⇒
plug in the and
values from the coordinate pair that passes through the line, which is (-4, -1). you can start with either
or
, but i'm going to start with
.
first, plug in for
.
⇒
now plug in for
.
⇒
after plugging in all of the given values, the equation is now , in which you need to solve for
.
now it's time to solve! begin by multiplying in order to simplify the right side of the equation.
you now have . subtract 1 from both sides of the equation. on the right side, it cancels itself out, leaving you with
. on the left side of the equation, you now have
, which equals
.
therefore , or
.
now that you've solved for your value, plug it into your initial slope-intercept form equation!
⇒
if you want to check to make sure that the values are correct, plug (-4, -1) into your completed slope-intercept form equation. as you did in the beginning, plug in for
and
for
.
⇒
begin simplifying by multiplying .
⇒
subtract .
⇒
since both sides of the equation are equal, that means your value of
is correct because it makes the equation true!
aaaand there you go! i hope this helps. have a great day! <3
