Find the slope of a line if the points (2,-1) and (5,3) are on the line
Romashka [77]

Answer:

\huge{ \boxed{ \sf{ \frac{4}{3} }}}

Step-by-step explanation:

\star{ \sf{ \: Let \: the \: points \: be \: A \: and \: B}}

\star{ \sf{ \: Let \: a(2,-1)  \: be \: (x1 \:, y1) \: and \: b (5,3)  \: be \: (x2 \:, y2)}}

\underline{ \sf{Finding \: the \: slope \: of \: the \: line}}

\boxed{ \sf{Slope =  \frac{y2 - y1}{x2 - x1} }}

\mapsto{ \sf{Slope =  \frac{3 - ( - 1)}{5 - 2} }}

\mapsto{ \sf{Slope =  \frac{3 + 1}{5 - 2}}}

\mapsto{ \sf{Slope =  \frac{4}{3} }}

Hope I helped!

The figure below shows the parcel of land on, which dallas, the zoo keeper , confines his zebras. His rule of thumb dictates tha
Irina18 [472]
Unfortunately, you haven't shared the "figure below" that shows the dimensions of this parcel of land.  Without being able to calculate the area of the parcel, you cannot really answer this question exactly.

Suppose that the area of the parcel were 6000 square meters.  Dividing that by 1500 square meters, we get 4, which represents the number of zebras that can live on this (example) parcel.

Figure out the area of your parcel, in square meters, and thend divide your result by 1500 square meters.  This will give your your answer.  Please note:  your answer will be a COUNT of zebras.  "meters" does not belong in this answer.
