4x-y=1 inslope intercept form please show work
shutvik [7]

Answer:

y = 4x - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

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

rearrange 4x - y = 1 into this form

add y to both sides

4x = y + 1 ( subtract 1 from both sides )

4x - 1 = y

y = 4x - 1 ← in slope-intercept form
