Example 3 Given the equation y = −28x The equation in the problem is in y = mx b form (also known as slopeintercept form), where b is the yvalue when x = 0, and m is the slope of the line m = −28; To write an equation when given the slope and yintercept, replace m with the given slope and b with the given yintercept in the equation y = mx b Example Write an equation in SlopeIntercept form given yintercept of (0,5) and slope = 2 (0,5) is the yintercept, therefore b = 5 Slope = 2, therefore m = 2 y = mx b y = 2x 58FA3 Interpret the equation y = mx b as defining a linear function, whose graph is a straight line; 1 Linear function y=mx+b examples
