Hi Kasey!

Here's your solution: Use Pythagoras' theorem to solve this problem:

a2+b2 = c2 (the ladder)

c2-a2 = b2 (height of wall)

100-16 = 84. The square root of 84 is 9.16515139

Therefore the ladder will reach 9 feet up the wall to the nearest foot.

G find the equation of the line (in slope intercept form) passing through the point (4,3) and parallel to the line passing throu
Yuki888 [10]

The points (1, 2) and (4, 2) both have the same y-value, so that is the horizontal line y = 2.


The given point has y-value of 3, so the line passing through it will be

... y = 3


_____

There is no x-term because the slope is 0. We could write it as

... y = 0x +3

but this simplifies to

... y = 3
