Stand Form of linear Equations Lesson 6-3 (continued) Stand Form of linear Equations

Review ax + bx = c y = mx + b SLOPE INTERCEPT FORM STANDARD FORM Equation:   y = mx + b ax + bx = c To Graph: Example:

Re-writing From Standard Form Slope Intercept Form To rewrite a linear equation written in standard form into slope intercept form Solve the equation for y Example: Write the equation in Slope Intercept Form 2x + 3y = 6

Your turn 3x -4y = 8 2. -x + 2y = 3

Graphing Horizontal and Vertical lines using standard from Write in standard form Graph Graph y = -4 Graph x = 2

Word Problem The sophomore class holds a car wash to raise money. A local merchant donates all of the supplies. A wash costs $5 per car and $6.50 per van or truck. a) Define a variable for the number of cars. Define a different variable for the number of vans or trucks.   b) Write an equation in standard form to relate the number of cars and vans or trucks the students must wash to raise $800.
