slope

y-intercept = - 1

#### Explanation:

The equation of a line in

#color(blue)"slope-intercept form"# is

#color(red)(|bar(ul(color(white)(a/a)color(black)(y=mx+b)color(white)(a/a)|)))#

where m represents the slope and b, the y-intercept.The advantage to having the equation in this form is that m and b may be extracted 'easily'

Rearrange

#y-3/5x=-1" into this form"# add

#3/5x" to both sides of the equation"#

#ycancel(-3/5x)cancel(+3/5x)=3/5x-1rArrcolor(red)(|bar(ul(color(white)(a/a)color(black)(y=3/5x-1)color(white)(a/a)|)))#

#rArr"slope" =3/5" and y-intercept" =-1#

graph{3/5x-1 [-10, 10, -5, 5]}
