line passes through (8,-6) and perpendicular to the line 2x+y= -7
slope of line p is -1/2
what is the equation of line p is y = 1/2x +

The weight of full–grown tomatoes at a farm is modeled by a normal distribution with a standard deviation of 18.4 grams. the 95 percent confidence interval for the mean weight of the tomatoes is calculated using a sample of 100 tomatoes. what is the margin of error (half the width of the confidence interval)?

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

Asystem of equations has 1 solution.if 4x-y=5 is one of the equations , which could be the other equation ?
