Need help with this question please
zubka84 [21]
We can use the two point form to find the answer:
y1 - y2 = m(x1 - x2)
Where y1 is the y coordinate(coordinate on the right hand side of (-9)) of the of the first coordinates, and y2 is the y coordinates of the second coordinates given (0).

While x1(-9) and x2(-6) are the x-coordinates(left hand side of the coordinates) of the coordinates given seperately.

m is the slope of the two points, and the formula is:
\frac{y1 - y2}{x1 - x2}
In this case:
\frac{ - 9 - ( 0)}{ - 9 - (-6)} \\ = \frac{ - 9 }{ - 9 + 6 } \\ = \frac{ - 9}{ -3 } \\ = 3

We can then proceed to find the eqaution by putting *one* of the points into the two-point formula.

Put (-6,0) into the formula:
-0-y = 3(-6-x)
-y = -18 - 3x
y = -(-18 - 3x)
y = 18 + 3x

Therefore the answer is y= 18+3x.

Hope it helps!

Calculate the length of a triangle if another length is 15 feet and the hypotenuse is 39 feet.
Y_Kistochka [10]
We have to use Pythagorean theorem that says : 

a^2+b^2=c^2\\\Rightarrow a^2+15^2=39^2\\a^2=39^2-15^2\\a=\sqrt{1296}\\a=36

The missing length of the triangle is : 36 feet
