Slope is –2 &amp; (5, 3) is on the line.<br> Y-Intercept:<br> Equation of the line (no spaces):
GREYUIT [131]

Answer:

The y intercept is (0,13)

The equation of the line is y = -2x+13

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

y = -2x+b

Substituting the point

3 = -2(5) +b

3 = -10 +b

Add 10 to each side

13 =b

The y intercept is (0,13)

The equation of the line is y = -2x+13

Can someone help me with this problem? ​
Ray Of Light [21]

Answer and Step-by-step explanation:

Answer is in picture.

We use the cosine trig function (adjacent side over hypotenuse = cos of an angle) to find m.

The angles are split perfectly in half, half of 90, which is 45, so the other angles are 45.
