Question

Find k if the slope of
4y= -kx - 2 is 4.

Answer 1

• k = -16

Explanation:

Given formula:

• 4y= -kx - 2, where slope is 4

Slope-intercept formula is:

• y = mx + b, where m is the slope

Finding slope by bringing the formula to the same format as above:

• 4y = -kx - 2
• y = -k/4x - 1/2

Slope is -k/4 and comparing it with the given:

• -k/4 = 4
• k = 4*(-4) = -16
