Find the slope of the line between (1,5)and (3,9)
Volgvan
We can use the points in either order and you will still get the same slope. I usually solve in order that is given. So the first coordinates I label (x1,y1) and the second is (x2,y2).

Slope=m=(y2-y1)/(x2-x1)
m=(9-5)/(3-1)=4/2=2

Slope is 2.

Someone can help???
frozen [14]

Answer:

The slant of the ladder is 5 ft

Step-by-step explanation:

Look at the attached figure to understand this situation

∵ a represents the distance from the edge to the top step

∵ The distance from the edge to the top step is 4 ft

∴ a = 4 ft

∵ b represents the distance to the house's edge from the bottom step

∵ The distance to the house's edge from the bottom step is 3 ft

∴ b = 3 ft

∵ c represents the slant of the ladder

∴ We need to find c

→ By using the Pythagoras Theorem

∵ c = \sqrt{a^{2}+b^{2}}

∴ c = \sqrt{(4)^{2}+(3)^{2}}=\sqrt{16+9}=\sqrt{25}

∵ \sqrt{25} = 5

∴ c = 5 ft

∴ The slant of the ladder is 5 ft
