Objective 1Find two points that satisfy the equation y 3x 2 and see whetherthey are points on the graph.If x 1, thenIf x 1, theny 3 • _______ _______y _______ _______y _______The point (_______, _______)satisfies the equation.y 3 • _______ _______y _______ _______y _______The point (_______, _______)satisfies the equation.The points (_______, _______) and (_______, _______) are both pointson the graph.The graph represents the function y 3x 2.The equation is a linear function because it is in the form y mx b. Its graphmust be a line. Since the graph is a line, it is a linear function.If x 0 and y 2, If x 2 and y 4,is the equation y 3x 2 true?is the equation y 3x 2 true?2 3 • 0 2 4 3 • 2 22 0 2 4 6 22 2 4 4Both points on the graph satisfy the equation.
