For the first one:

m is the slope, or how much the line goes up compared to goes right.  In this case, the line goes up 40 every time it goes right 10.  We write this as a fraction so 40/10, which simplifies to 4.  Therefore the equation would be y = 4x.

I’m not sure the answer. help!!

Answer:

  x = {-5π/4, -3π/4, 3π/4, 5π/4}

Step-by-step explanation:

You know that sec(x) = 1/cos(x), so this is equivalent to ...

  cos(x) = -1/√2

The cosine has a magnitude of 1/√2 for an angle of 45°, or π/4 radians. It is negative in the 2nd and 3rd quadrants. Angles in those quadrants that have a reference angle of π/4 are ...

  3π/4, 5π/4

We also want angles in the range -2π to 0, so all of the solutions will be ...

  sec(x) = -√2 for x = {-5π/4, -3π/4, 3π/4, 5π/4}

__

We like to use the x-intercept as the solution when graphing, so we write the given equation as ...

  sec(x) +√2 = 0

The graph verifies the above solutions.
