Substitute x by 3 + y in the equation - 5 x - 2 y = -22 and solve for y Equation x - y = 3 can be solved for x to give To find the point of intersection of the two lines, we need to solve the system of equations x - y = 3 and -5 x - 2 y = -22 simultaneously. What is point of intersection of the lines x - y = 3 and - 5 x - 2 y = - 22?Ī point of intersection of two lines is solution to the equations of both lines. Set y = 0 in the equation and solve for x. What is the x intercept of the line - 3 x + y = 3? Set x = 0 in the equation and solve for y. What is the y intercept of the line - 4 x + 6 y = - 12? Set a = - 1 and b = -2 in the given expression and evaluate.ģa 3 - 4b 4 = 3(-1) 3 - 4(-2) 4 = 3(-1) - 4(16) = - 3 - 64 = - 67Īdd -1 to both sides of the inequality and simplify.įor what value of the constant b does the linear equation 2 x + b y = 2 have a slope equal to 2?.

Set a = - 3 and b = 5 in the given expression and evaluate.

Substitute a and b by their values and evaluate.
