The answer should be (x, y) —> (x - 8, y + 10)
Answer:
y+4 = 3(x -1)
Step-by-step explanation:
You are given two points, so you only need to find the slope. The slope is given by the formula ...
m = (y2 -y1)/(x2 -x1)
m = (2 -(-4))/(3 -1) = 6/2 = 3
The point-slope equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
Using the first point, the equation is ...
y+4 = 3(x -1)
4 ft below sea level : -4
3 ft below sea level : -3
Use the quadratic formula:
When you solve the problem you get m=26/5 and then you have to make it into a decimal. And 26/5 is 5.2
