Question

Extra Practice: Identify the point used in

the equation:
y-5 = 1/2(x-4)
Thes
(4,5)
None of the above
(-4,-5)
(1, 2)
(2.1)

Answer 1

(a) (4, 5)

Explanation:

The point-slope form of the equation for a line is ...

y -k = m(x -h) . . . . . . where m is the slope and (h, k) is the point

Comparing this to

y -5 = 1/2(x -4)

we see that k=5, m=1/2, h=4. Then the point is ...

(h, k) = (4, 5)
