Question

Which of
below equations has a graph that passes
through the points (2, 3) and (0,-1) ?

Answer 1

D

Explanation:

Point slope formula y-y1=m(x-x1)

slope formula y1-y2/x1-x2

Points provided (2, 3) and (0,-1)

Let's find the slope. To find slope we need to plug in our numbers in the slope formula (y1-y2/x1-x2)

3-(-1)/2-0

4/2

=2

so slope (m) is 2

Now let's plug this in our point-slope formula (y-y1=m(x-x1)) with one pair of points (2,3)

y-3=2(x-2)

so, therefore, our answer is D!
