Answer:
y - 4 = (2/3)(x - 7)
Step-by-step explanation:
(see attached for reference)
we are given slope, m = 2/3 and point (x₁, y₁) is (7,4)
y - y₁ = m(x - x₁)
substituting the given values into the general equation
y - y₁ = m(x - x₁)
y - 4 = (2/3)(x - 7)

Answer:
cos(63)=y/15
tan(27)=y/x
sin(63)=x/15
Step-by-step explanation:
You need to memorize the definitions of all the trig functions. Then these types of problems will be easy for you. OK?
