+ Warm Up 1) y = 4x – 5 a) Find Slope and y-int b) Graph 2) y = -2/3x + 4 a) Find Slope and y-int b) Graph 3) You start with $15 in your bank, and add $10 a week. Write an equation. How much will you have in 20 weeks + Standard Form Introduction and Graphing Standard Form: Ax By C Where A, B, and C are coefficients, and x and y are our variables. + X & Y Intercept y – intercept: Where the line crosses the y axis (X IS ZERO) x – intercept: Where the line crosses the x axis (Y IS ZERO) + Finding X&Y Intercepts 5x – 4y = 20 + Finding X&Y Intercepts x – y = 10 + Finding X&Y Intercepts 3x + 8y = 16 1)x – 3y = 6 2) 2x + y = 4 3) 5x – 2y = 10 1) x – 2y = -4 2) x + 2y = 0 3) 2x + 3y = 6 4) 2x + y = 1
