Question 757027
Slope-intercept form for a line:
y=mx+b
m is the slope
b is the y-intercept for point (0, b).


You could solve the equation in its most general form for b:
{{{y=mx+b}}}
{{{y-mx=mx+b-mx}}}
{{{y-mx=mx-mx+b}}}
{{{y-mx=b}}}
{{{b=y-mx}}}


Use that formula for b now because you were given a point and the slope.
{{{b=-4-(-3/5)*5}}}
{{{b=-4+3}}}
{{{b=-1}}}


Back again the the slope-intercept form for a line, 
y=mx+b
You were given the slope, and you found the value for b, so you just put them in their positions in the equation.
