Question 775470
so basically they gave you two points where the line crosses x and y axis, y intercept means x values is 0 so(0,3) and x intercept means y value is zero so (-10,0)
now you have two points so you can find the slope using the slope formula
{{{m=(y2-y1)/(x2-x1)=(0-3)/(-10-0)=3/10}}}
next you can use the formula for the line when you have a slope and a point, the formula is 
y-y1=m(x-x1) where m is the slope and (x1,y1) is a point given (you can use either of the two, i'll use (0,3)
{{{y-3=(3/10)(x-0)}}}
{{{y-3=3x/10}}} now we need to put it in slope intercept form so add 3 to each side
{{{y=3x/10+3}}}
