Problem

Find the slope of the line passes through the points:
\$ (1,8),(5,12) \$

Step

Consider given points as (x_1,y_1) and

\$(x_2,y_2)\$

Step

equating the terms

\$ x_1=1,y_1=8 and x_2=5,y_2=12 \$

Formula:

By using slope formula

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

Step

by simplifying

\$ m = (12 - 8) / (5 - 1) \$

Step

After simplification we get

\$ m = \cancel4^1/\cancel4^1\$

Step

After cancellation we get

m = 1
