Question

Which of the following equation has a slope of -2 and y-intercept of -3/2? *

1 point

A. 4x + 2y = 3

B. -4x + 2y = -3

C. 2y + 4x = -3

D. 2y – 4x = 3

Answer 1

C is correct

solve each equation in the form y=mx+b. m=slope b= the intercept. y=-2x -3/2

only C can be solved for y and get -2x-3/2

slope =-2, the coefficient of the x term when the equation is solved for y

when solved for y, the constant term is the y intercept

B has a y intercept of -3/2 but it's slope is 2, not -2

A and D have the wrong intercept
