Question

20 POINTS

A line passes through the points (3,7) and (4,9), Find the equation of the line in slope-intercept form and also in standard form.

Answer 1

slope =(9-7)/(4-3) = 2
equation
y - 7 = 2(x - 3)
y - 7 = 2x - 6
y = 2x + 1 .....this is slope intercept form
2x - y = = -1 .....this is standard form
