I assume you want the equation in point slope form? So assuming that, (0, 5) is the y intercept which is b in the equation y=mx+b (b=5). Now you have to find the slope, paper is really handy (I like drawing a graph out to help me sometimes but an easy way to do it is another equation like this...
y2-y1/x2-x1=
7-5/-5-0=
2/5 --> So 2/5 is the slope, and that finishes the equation
<span>Pru and Piper have apples is ratio 5:3
Let No. of apples with Pru = 5a
and no. of apples with Piper = 3a
and no. of apples with Phoebe = 4a
5a - 3a = 24
2a = 24
a=12
No. of apples with Phoebe = 4x12=48
Hence Phoebe has 48 apples.</span>
