Given the slope of the line and a point on the line, find an equation for each line.
- A line of slope 4 passing through the point (0,2)

I remember rise over run and y=mx+b but how do I apply that to this question?

Solve the equation.

17-4e^-3t = 8

I ended up getting a non-real answer. I ended up trying to take the natural log of -25/4 and I get a non-real answer in my calculator. Did i do something wrong?

Where 'P' is a matrix and 'x' is a vector:

Px = the projection of x onto <1,1>. What is the the matrix P relative to the basis { <1, -1>, <1,1>}

I'm thought the answer was:

| 0 1 |
| 0 1 |

Because the projection of <1, -1> onto <1,1> is <0,0> and the projection of <1, 1> onto <1,1> is <1,1>, but my choices are

| 2 1 |
| 1 2 | - A

| 1/2 1/2 |
| 1/2 1/2 | - B

| 0 0 |
| 0 1 | - C

and

| 1 0 |
| 0 0 | - D

---

| a d |
| b c | is the matrix for T relative to the standard basis. What is the matrix for T relative to the basis {<0, -1>, <1, 0>}

I'm completely stumped on this one. Even if someone could just nudge me in the right direction i would be appreciative... Thanks!

For example

a) 1653x ≡ 77(mod 2000)
b) x^2 ≡ 4x (mod 12)

which ones of these have solutions sand why...and how do you know what the complete solution is

thanks
