Question

Write an equation for the line that passes through (3,1) and (6,4).

Answer 1

Find the slope using the slope formula: \[\frac{Y _{2} - Y _{1}}{X _{2} - X _{1}}\]
Next use the point-slope formula: \[y - y _{1} = m (x - x _{1})\]and plug in either set of coordinations for the y and x values.

Answer 2

4 - 1 = 3
6 - 3 = 3
m = 1

y - 1 = 1 (x - 3)
y = x - 2
