Answer:
y = 3/4 x -1
Step-by-step explanation:
The equation for a line with the slope and the intercept is y = mx+b where m is the slope and b is the y intercept
y = 3/4 x -1
This is something to memorize
y = r*sin(theta)
so if y = 2, then
2 = r*sin(theta)
Divide both sides by sin(theta) to get
r = 2/sin(theta)
r = 2csc(theta)
