Question

a straight line ab passes through the points a(3,2) and b(7,10).find the slope of ab and state that whether it slopes upward from left or downwards from left

Answer 1

In order to find the slope, we may use the formula:

Slope = (y2−y1)/(x2-x1)

Now, let's identify the values. Say, point a is the first point and b is the second. This means that:

x1 = 3

y1 = 2

x2 = 7

y2 = 10

Let's plug in the values:

=(10-2)/(7-3)

=8/4

=2

Now, to determine if the slope is downward or upward, positive slope means upward from left to right while negative slope means downward from left to right.

So since our slope is positive 2, it is upward.

FINAL ANSWER:

Slope = 2

It slopes upward from left to right.
