Slope of the line that passes through (1, 4) and (1, −3)?

The slope of our given line is undefined.

Step-by-step explanation:

We are asked to find the slope of line that passes through points and .

We will use slope formula to solve our given problem.

, where,

= Difference between two y-coordinates,

= Difference between two x-coordinates of same y-coordinates.

Let and .

Since x-coordinates of both points are same, this means that our given line is a vertical line, therefore, the slope of our given line is undefined.

answer:   rlly

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
