How to find the slope and y intercept from two coordinate pairs

Slope: y2-y1/x2-x1

Step-by-step explanation:

You find slope from two coordinate pairs by using the slope formula(y2-y1/x2-x1) or rise over run from a graph.

To find y-intercept, x needs to be 0 on a graph.

Given Suzie profits increase by 30% over what they were the previous week.

Profit made by Suzie in first week = $300

She makes a profit of 30% =0.30 over what they were the previous week .

Profit made by Suzie in second week = 300+.30(300)= 300+90=390

Profit made by Suzie in third week = 390+.30(390) =390+117=507

Profit made by Suzie in fourth week = 507+.30(507)= 507+152.1 =659.1

Total profit made = 300+390+507+659.1= 1856.1

Profit Suxie make in all over 4 weeks =$1856.10 .
