Question

What is an equation of the line that passes through the points (4,4) and (8.1)

Answer 1

• y = - 3/4x + 7

Explanation:

Use both points and find the slope:

• m = (1 - 4) / (8 - 4) = - 3/4

Find the line, using point-slope form and point (4, 4):

• y - 4 = - 3/4(x - 4)
• y - 4 = - 3/4x + 3
• y = - 3/4x + 7
