Answer:
Step-by-step explanation:
Step 1. Find the slope (by using the slope-formula)
m = slope
Step 2. Write the equation (using the slope and the points)
Here's how to do it:
Slope-intercept Formula whrere m = slope and b = y-intercept
Plug in the slope into the Slope-intercept Formula
Find the y-intercept (b) by using a point and substituting their x and y values
Point: (3, 7)
Step 3. Write the equation in Slope-intercept form
The values of sin θ and cos θ represent the legs of a right triangle with a hypotenuse of 1; therefore, solving for cos θ finds the unknown leg, and then all other trigonometric values can be found.
