\bold{\underline{\frak{\pink{\;given\;}}}}

Ray BD bisects ∠ABC so that m∠ABD = 5y – 3 and m∠CBD = 2y +12.

\bold{\underline{\frak{\pink{\;to\;find}}}}

Find the value of y.

\huge{\underline{\frak{\red{\;solution\;}}}}

bisect" means to cut into equal parts.

Thus: 5y – 3 = 2y +12

#2 , let the endpoint be (x,y)

for the x:

(4+x)/2 = 2

4+x = 4

x = 0

for the y:

---- your turn

#3, just use your "distance between 2 points" formula

PLEASE HELP!!!Which equation goes through the point (-7, 3) and is parallel to y = −8x + 1?
Blizzard [7]

Answer:

  y - 3 = -8(x + 7)

Step-by-step explanation:

The equation of a line with slope m through point (h, k) is ...

  y -k = m(x -h)

__

The slope you want is m = -8, which is the slope of the given line.* The given point is (h, k) = (-7, 3), so the equation you're looking for is ...

  y - 3 = -8(x -(-7))

The expression inside parentheses can be simplified so you have ...

  y - 3 = -8(x + 7)

_____

* The given line is in "slope-intercept" form, which is y = mx + b. Matching this pattern to the given equation, you see that m=-8. Parallel lines have equal slope, so -8 is the slope of the line you're writing the equation for.
