Find the equation (in terms of x) of the line through the points (-3,0) and (4,5)
Y=?​

Step-by-step explanation:

steps are in the picture above.

m∠a is 90°

m∠b is 40°

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
