Some people use SOH - CAH - TOA to remember the trigonometric ratios for sine, cosine, and tangent. Why do you think that word might help?

hope this is helpful

Step-by-step explanation:

SOH-CAH-TOA is really helpful in remembering what each of the ratios should look like.

For sine, SOH means --> Sine- Opposite- Hypotenuse

This helps to remember that when using sine, you should use the Opposite length over the Hypotenuse in your ratio.

For cosine, CAH means --> Cosine- Adjacent- Hypotenuse

Your ratio should have the Adjacent length over the Hypotenuse

For tan, TOA means --> Tangent- Opposite- Adjacent

Your ratio should have the Opposite length over the Adjacent length  

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
