Answer:

y = 4x +5

Slope is 4

Intercept is 5

Step-by-step explanation:

Using, y1= 1 and x1= -1

And, y2 = 13, x2 = 2

$\frac{y2 - y1}{x2 - x1} = \frac{y - y1}{x - x1}$

$\frac{13 - 1}{2 - ( - 1)} = \frac{y - 1}{x - ( - 1)}$

$\frac{12}{3} = \frac{y - 1}{x + 1}$

$4 = \frac{y - 1}{x + 1}$

$y - 1 = 4(x + 1)$

y-1 = 4x +4

y = 4x +4 +1 = 4x +5

What is cos theta of tan theta= 8/5?

snow_lady [41]

I'd suggest you write:

":<span>What is cos theta IF tan theta= 8/5?

tan theta = opp / adj = 8 / 5, so we know that opp = 8 and adj = 5. Then the length of the hypotenuse is sqrt(8^2+5^2) = 9.43.

Thus, the cosine of theta / cosine of this angle is

adj 5
----- = ---------- , or about 0.53.
hyp 9.43</span>
