Below is a review of equations of lines.Forms of Linear EquationsAx + By = C Standard form of a linear equation. A and B are not both 0.y = mx + b Slopeintercept form of a linear equation. The slope is m,and the y-intercept is (0, b).y - y1 = m1x - x12 Pointslope form of a linear equation. The slope is m, and1x1 , y12 is a point on the line.y = c Horizontal line The slope is 0, and the y-intercept is (0, c).x = c Vertical line The slope is undefined and the x-intercept is (c, 0).Parallel and Perpendicular LinesNonvertical parallel lines have the same slope. The product of the slopes of twononvertical perpendicular lines is -1. Graph each linear equation. x = -3
