Take the three and divide it with the 12 which would get you 4 so put a open circle Above the 4 and make the line go to the left I think I hope this will help

Please help me this question

Annette [7]

Step-by-step explanation:

Hey there!

The given point is (8,-3) as (x1,y1) and slope (m) = -3/4.

Note: use one point formula for finding the equation.

$(y - y1) = m(x - x1)$

Put all values.

$(y + 3) = - \frac{ 3}{4} (x - 8)$

Simplify it.

$(y + 3) = - \frac{ 3}{4} x - 8 \times - \frac{3}{4}$

$(y + 3) = - \frac{3}{4} x + 6$

$y = - \frac{3}{4} x + 6 - 3$

$y = - \frac{3}{4} x + 3$

Therefore, the equation is; y = -3/4x+3.

Hope it helps...

What is an equation of the line that is perpendicular to y-3=4(x+2) and passes through the point (-5,7)

gtnhenbr [62]

Answer:

The perpendicular line would be y = -1/4x + 23/4

Step-by-step explanation:

In order to find the equation of this line, we first have to note that perpendicular lines have opposite and reciprocal slopes. Therefore, since the original line has a slope of 4, we know the new line will have a slope of -1/4. Now we can use that information along with the given point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - 7 = -1/4(x + 5)

y - 7 = -1/4x - 5/4

y = -1/4x + 23/4
