Question

Need help with point slope form

Answer 1

Hi there!

To find your answer, simply sub in the point and the slope into y-y1=m(x-x1) for y1, x1 and m!

m=-8
point: (1,-8) use this point for x1 and y1
y+8=-8(x-1)

Therefore your equation is y+8=-8(x-1)

Hope this helps!

Answer 2

Hey there!

A line passing through a point $(x_1,y_1)$ and with a slope of $m$ will have the following equation in point slope form:

$y-y_1=m(x-x_1)$

According to the given information, we know the following:

$(x_1, y_1)=(1,-8)$
$x_1=1$
$y_1=-8$

$m=-8$

Now, we can just plug in this information into the equation of $y-y_1=m(x-x_1)$

$y-(-8)=-8(x-1)$

Simplify

$y+8=-8(x-1)$

That's your answer. Have an awesome day! :)
