Write the equation of the line perpendicular to y = 4x +3 with a y-intercept (0,2).

If n stands for number sold and c stands for cost per item, in which column would you use the formula: ? a. column d c. column f b. column e d. column g

What is the equation of the line in point-slope form? y+ 4 = 1/2(x+4) y-4 = 1/2(x + 4) y-0 = 2(x - 4) y-4 = 2(8-0)

Determine if the equation defines y as a function of x: 2xy = 1. yes o no
