X-and Y-intercepts

Standard Form (of a linear equation) ax + by = c, where a, b, and c are integers

Standard Form:Not standard: 2x – 5y = 70.5x + 4y = 12 4x + 9y = 0y = 3x – 2 y = 3 x + y – 1 = x – y Nonlinear: x 2 y + 3y = 4 xy = 6 (1/x) + 3y = 1

X-intercept- where the graph crosses the x-axis (where y = 0) Y-intercept- where the graph crosses the y-axis (where x = 0)

State the x-intercept and the y- intercept of each line.

Find the x- and y-intercepts of the line. 2x + y = 10 X-int:Y-int: Let y = 0Let x = 0 Now graph:

Find the x- and y-intercepts of the line. y = 3x – 2 X-int:Y-int: Let y = 0Let x = 0 Now graph:

Graph the equations: 1)x = 4 2)y = -2
