We knownthe equation of a line is y = mx + b. where m is slope and b is y intercept.
the point slope equation of a line is y - y1 = m (x - x1)
plug in x1 and y1 and m
y- (5) = (3)(x - (-1))
y - 5 = 3x + 3
y = 3x + 8
the answer is D you get this from using simultaneous equations the working out is shown in the photo. ignore the stuff at the top of the page
Answer:
The answer is 9.
Step-by-step explanation:
The derivative of a function like this is computed with the following formula:
