Georgia [21]

Answer:

Yes they can all be written in y = mx + b. You just have to move the terms around.

Step-by-step explanation:

y = 2x -3, this is already in slope-intercept form

Now, y - 2 = x + 2: We can add 2 on both sides to cancel out the one on the left side:

y - 2 = x + 2

y - 2 + 2 = x + + 2

y = x + 4 <-- This is in y = mx + b form

Now the last one, 3x = 9 + 3y

We can first divide all terms by 3,

3x = 9 + 3y

/3     /3   /3

x = 3 + y: Then we can subtract 3 from both sides:

x - 3 = 3 + y - 3

x - 3 = y

These are all linear equations because none of the x's have bigger powers than 1. x^2 is a quadratic equation and x^3 is cubic equation.

About 0.3 degrees, by estimation.  
The sixty-to-one rule is useful here.  At a distance of 60 units, the angle in degrees and the distance (in units) are about equal for small angles.  
Thirty to two inches is the same as sixty to four inches, about a third of a foot, so the angle must be about a third of a degree.  Rounded it gives 0.3.
