Answer:

m =(Y²-y¹)÷(x²-x¹)

= (-12 -8 )÷(3-1)

= (-12 -8 )÷(3+1 )

= -20/4

= 5

Answer:

-5

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

=(-12 -8)/(3 - -1)

=(-12-8)/(3+1)

= -20/4

= -5

A-line includes the points (8,9) and (9,1). What is its equation in point-slope form?

Answer:

$y-(9)=(-8)(x-8)\\$

Step-by-step explanation:

$(x_1, y_1) = (8, 9)\\(x_2, y_2) = (9,1)\\$

Step one: Find the slope (m)

$slope=m=\frac{rise}{run} =\frac{y_2-y_1}{x_2-x_1} = \frac{1-9}{9-8} =\frac{-8}{1} =-8$

Step two: Plug your known values into the point-slope equation

$m=-8\\y_1=9\\x_1=8\\$

Point-slope form is $y-y_1=m(x-x_1)$

$y-(9)=(-8)(x-8)\\$

If you want to convert point-slope form to general form, isolate for y.

$y-9=-8x+64\\y=-8x+73$

Find what y equals please (geometry) :)

pychu [463]

Answer: y=31.97°

Explanation: We can use trig ratios to find y and they are SohCahToa.

We can use Sin y, because when y is the reference angle, the 9 cm side is the opposite and the 17cm is always the hypotenuse.

We must take the inverse of Sin (9/17) to get about 31.9657, which we can round to 31.97°.
