Tuesday, September 10th Please complete the warm up Solve:

Is (3,4) a solution to the following system: 3x-4y=12 and -4x=y+2

Do you know your Vocab?System of Linear EquationsSolution of a system of linear equationsSlope Intercept Form Y = mx + b SlopeY-interceptGraphingY=mx + b mRise Over _____________bThe _________intercept

Its where you _____ your graph

REVIEW ON RISE AND RUNDESCRIBE how you would graph given the following slope

Slope = -3Down 3Right 1Or Up 3 Left 1


y intercept = 4Step 1. The y-intercept is 4, so the line contains (0, 4). Plot (0, 4).Step 3 Draw the line through the two points

Run = 5Rise = 2Step 2 Slope = Count 2 units down and 5 units right from (0, 4) and plot another point.

yJust Watch

Y = -3x = 4 What is the slope?3 5x = y What is the y-intercept?What is the Slope?

What is the Equation that represents this line?

Slope Intercept Word ProblemSam and Joe are collecting baseball cards. Sam already had 5 baseball cards and is given 4 new cards each year. Joe only started with 3 baseball cards but is given 6 new cards each month. After how many months will Same and Joe have the same amount? How many cards will they have at that time?
