It’s 4, because ththey go by fours because of the way they go up.
The equation of a line in point slope form =
To put
into function notation, we need to get y by its self.
Lets say we had a point (2,2) and a slope of 3. Ok, now that we have our point and slope, lets turn point slope form into function notation.
Change the y to f(x)
<-----Function notation.
Slope-intercept form is y=mx+b, so we simply have to solve for y...
3y+5x=-15 subtract 5x from both sides
3y=-5x-15 divide both sides by 3
y=-5x/3-5 or more neatly in my opinion...
y=(-5x-15)/3
3d + $5.25 = $38.22
3d= $38.22-$5.25
= $32.97
d= 32.97/3
=$10.99
