Linear Relations Quiz 9D

What is the slope-intercept form of a linear equation?

• y = bx + m

• y = mx - b

• y = mx + b

• y = ax + b

How do you graph a linear equation in the form y = mx + b?

• Start at the highest point on the graph and use the slope (m) to find additional points and connect them to create the line.

• Use the x-intercept (b) as the starting point, then use the slope (m) to find additional points and connect them to create the line.

• Plot the points randomly on the graph and then connect them to create the line, ignoring the slope and y-intercept.

• Use the y-intercept (b) as the starting point, then use the slope (m) to find additional points and connect them to create the line.

What is the equation of a line with a slope of 3 and a y-intercept of 2?

• y = 3x - 2

• y = 2x + 3

If the slope of a line is 1/2 and it passes through the point (3, 4), what is the equation of the line?

• y = (1/3)x + 4

• y = (3/2)x + 4

• y = 2x + 3

• y = (1/2)x + 3/2

Graph the linear equation y = -2x + 4

• The graph of the linear equation y = -2x + 4 is a parabola
