Question

Using the point-slope formula, what is the equation of the line that passes through the points (1,5) and (0, 0)?

O A. y = 5x
OB. y = 5x + 10
O C. y = x
OD. y = 5x - 1

Answer 1

y =5x

Explanation:

`y_(1)-y_(2) = m(x_(1) - x_(2) )`

(5 - 0) = m(1 - 0)

5 = m(1)

5 = m

`y_(1)-y_(2) = m(x_(1) - x_(2) )`

y - 5 = 5(x - 1)

y - 5 = 5x - 5

y = 5x -5 + 5

y = 5x
