Question

Which of the following is the equation of a line in slope-intercept form for a line with slope=5 and y-intercept at (0,-3)

Answer 1

y = 5x - 3

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = 5 and c = - 3

y = 5x - 3 ← equation in slope-intercept form

Answer 2

The equation of a line in slope-intercept form is :
`y=5x-3`

Explanation:

Slope intercept from = y = mx+c

Given : point on the line (0,-3),

Slope of the line = 5

Point slope form :

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

`(y-(-3))=5* (x-0)`

`y+3=5x+0`

`y=5x-3`

(y = mx+c)

The equation of a line in slope-intercept form is :
`y=5x-3`
