Question

Which of the following is the point-slope form of the equation of the line with slope 4

that crosses the point (1, 3)?
Oy-1= 4(x – 3)
Oy+1= 4 (2+3)
Oy-3= 4(x - 1)
Oy+3 = 4(x+1)

Answer 1

Third option

`y-3=4(x-1)`

Explanation:

Equation of straight line in point slope form is given as

`y-y_1=m(x-x_1)`

Here

slope=m=4 and
`(x_1, y_1) = ( 1, 3 )`

Equation of straight line having slope 4 and crossing from point (1, 3) is given as

`y-3=4(x-1)`
