 Question 446983: Hello , my name is Victoria and i need help with my Pre-Algebra homework , & it would be kindly appreciated if you could help . In class we have been working on how to find the slope , But in class my teachers gives us graphs and charts so we can figure out the y intercept . & on our homeowrk it doesnt show that and i dont know how to find the y intercept of 2/3 x . i know the formula y=mx + b which m is the rate which would be 2/3 so it would be y=2/3x + b which is the y intercept . & i cant figure out the y intercept without a graph or a table & i dont understand how to make either one of those with all i know from this problem that its rise over run which is 2/3 . hopefully you can help , Thank you .
