What is the slope and the y-intercept?

To do this you want to isolate the y value. First, add 5x to both sides, so that it becomes 3y = -9 + 5x. Then, divide both sides by 3. You get -3+5x/3, which is equal to
Y=5x/3 -3 so the y intercept (where x is zero) would be -3, and the slope is 5/3

Change to slope intercept form.

Add 5x to both sides.

-5x + 5x + 3y = -9 + 5x

3y = 5x - 9

Now divide by 3.

y = 5/3x - 3

Remember that slope intercept is in the format y = mx + b 
m = slope
b = y-intercept

Good luck, that should do you good :)

B.the point lies directly on the regression

Answer: b 2 = 1.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

therefore, b 2= 1.
