What is the equation of the line
passing through (-3,-1) having slope
4?

The answer is

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

where

m is the slope

( x1 , y1) is the point

From the question we have

We have the final answer as

Hope this helps you

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
