Question

Line ab passes through points a(-6,6) and b(12,3). if the equation of the line is written in slope-intercept form, y=mx+b, then m= -1/6. what is the value of b?

Answer 1

Answer: 5

Explanation:

We have the equation of the line is of the form
`y=-(1)/(6)x+b`.

Substituting in the coordinates (12,3), we get that:

`3=-(1)/(6)(12)+b\\\\3=-2+b\\\\b=5`
