astra-53 [7]2 years ago
3 0

Answer:

A. y - 4 = 3(x + 2)

Step-by-step explanation:

Point slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line

Plug in the slope and given point:

y - y1 = m(x - x1)

y - 4 = 3(x + 2) is the equation

So, A is the correct answer.

The sum of two number is 13 and their product is 42 then what are the two numbers​
Vaselesa [24]

Answer:

6 and 7

Step-by-step explanation:
