Question

Find the equation of the line passing through the points (3, 3) and (4, 5). y = [? ]x + [ ] ​

Answer 1

• y = 2x - 6

Explanation:

Given points

• (3, 3) and (4, 5)

Slope is:

• m = (5-3)/(4-3) = 2/1 = 2

Using point (3, 3) to find the y-intercept

• 3 = 3*3 + b
• b = 3 - 9
• b = -6

The line is

• y = 2x - 6
