Question

If a line passes through 3,0 and 0,-3 what is the slope of the line

Answer 1

1

Given :

• P = (x¹,y¹) = (3,0)
• Q =(x²,y²) = (0,-3)

To find :

• The slope of the line

Solution:

Let the slope of the line be m.

we know that ,

• m = (y²-y¹)/(x²-x¹)

inserting the values provided in the formula,

• m = (-3-0)/(0-3)
• m = -3/-3
• m = 1

Therefore,the slope of the line would be 1 .

Answer 2

m=1

Explanation:

Given:

Passes through (3,0) and (0,-3)

let

`(x_1,y_1)=(3,0)`

`(x_2,y_2)=(0,-3)`

To find:

Slope(m)=?

We have,

`m=(y_2-y_1)/(x_2-x_1)`

where,

`(y_2 - y_1)` is the change in the y-coordinate between two points on the line

`(x_2 - x_1)` is the change in the x-coordinate between two points on the line

Substituting value:

`m=(-3-0)/(0-3)`

`m=(-3)/(-3)`

m=1

Therefore, slope is 1.
