Text Solution

Verified by Experts

Angle made by the line with the positive direction of X-axis
` (theta) = square `
Slope of the line `square `
= `tan square `
` = square " " ` ( Writing the value )
Slope of the line is `square `
Angle make by the line with the positive direction of X-axis
Slope of the line =
`(theta)=45^(@)`
Slope of the line `= tan theta `
`= tan 45^(@)`
`=1 ` ... (Writing the value )
Slope of this line is 1 .
