Y=mX+b where m=slope & b=the Y intercept.
10x=3y+15
3y=-10x+15
y=-10x/3-15/3
y=-10x/3-5 m=-10/3 & b=-5

sol:
the equation of the line is of the form ax+by+c=0
then the slope= -(x coefficient/y coefficient)= -(a/b)
x-intercept= -(c/a)
y-intercept= -(c/b)
now convert the equation is of the form ax+by+c=0
given equation is
10x=3y+15
subtract 3y and 15 on both sides
10x-3y-15=3y+15-3y-15
10x-3y-15=0
now the equation of the form ax+by+c=0
here
a=10 ,b= -3, c= -15
slope=-(a/b)= -(10/-3)=-(-10/3)=10/3 (.e;-*-=+)
y-intercept=-(c/b)=-(-15/-3)= - (15/3)= -15/3 (i.e;-/-=+, -*+=-)
slope=10/3,y-intercept= -15/3
