1-4 Writing Linear Equations Pre Calc A
Slope Intercept Form vs. Standard Form • Ax + By = C • A must be positive • A, B, C, must be integers
Ex 17: • Write an equation in slope-intercept form for each line • A. slope of ½ and a y- int of 4 • B. slope of 2 and passes through the point (-3, 2)
Ex : • Mr. Bricker is preparing his art classroom for the school year. He placed a purchase order for $800 to buy paper, chalk, and clay. In addition, he expects the expenses each month to be $120. Write an equation that models the total expense y after x months. • Use that equation to predict Mr. Bricker’s expenses after 6 months.
Ex last one: • Write and equation in standard form of the line that passes through (5, 2) and (7, 9)
