Exercise 51 Page 144

If the equation of a line is written in slope-intercept form, the slope is given by the coefficient of the x-variable.

k=1/8

Practice makes perfect
Equations in slope-intercept form follow a specific format. y= mx+ bIn this format, m is the slope and b is the y-intercept of the line. We need to find the value of k that makes the given equation to have a slope of 12. y= 4kx-5 ⇔ y= 1/2x-5 We can find this value by setting 4k equal to 12, and solving the equation.
4k=1/2
k=1/2 ( 1/4 )
k=1/8
