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

hello :

note : The equation of a linear function in point-slope form is : y – y1 = m(x – x1)

The point is A (x1 , y1)

Explanation:

in this exercice : m = 5 x1 = 0 y1 = -3

the equation of a line in slope-intercept form for a line is :

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

y +3 = 5 ( x - 0)

Answer 2

`y=5x-3`

Explanation:

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

Slope intercept form of a line is
`y=mx+b`

where m is the slope and b is the y intercept

given slope =5 and y intercept
`b=-3`

now plug in the values in the slope intercept for
`y=mx+b`

`y=5x-3`
