Problem

Find the slope of the line passes through the points:
\$(2,-4),(7,-9) \$

Step

Consider given points as (x_1,y_1) and

\$(x_2,y_2)\$

Step

equating the values

\$ x_1=2,y_1=-4 and x_2=7,y_2=-9 \$

Formula:

By using slope formula

\$ slope(m) = (y_2 - y_1) / (x_2 - x_1)\$

Step

by simplyfying

\$ m = (-9 - (-4)) / (7 - 2) \$

Step

After simplification we get

\$ m = (-9 + 4) / 5\$

Step

After simplification we get

\$ m = -\cancel5^1 / \cancel5^1\$

Step

After cancellation we get

\$ m = -1\$
