Question 3 (1 point)

A line passes through the point (2.3) and has a slope of 3. What is the equation of the line in
slope intercept form?

Answer 1

y = 3x - 3

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (2, 3) into the partial equation

3 = 6 + c ⇒ c = 3 - 6 = - 3

y = 3x - 3 ← equation of line
