Answer 2
Not sure if this is what you’re looking for but when you have a less than or greater than sign, the circle is open.

When you have a less than or equal to or a greater than or equal to sign, the circle is colored in, or referred to as closed.

what is m = 2/3; (6, 1) in slope intercept form? :)

Answers

Answer:y=6x-16y=6x-16

Step-by-step explanation:

y = 2/3x - 3

Slope-intercept form looks like this: y = mx + b. m is your slope (in this case 2/3), and b is your y intercept.

Here, you already know the slope so you can plug it into the equation

y = 2/3x + b

To find b, plug in your point ((6,1)) in for x and y and then solve for b

1 = 2/3(6) + b
1 = 4 + b | multiply 6 x 2/3
-3 = b | subtract 4 from both sides

Now, plug b into your equation and you’re all set!

y = 2/3x - 3
