Question

What is the equation in point slope form of the line that passes through the point (1 , 8) and (2 , 10)

Question 11 options:

y+8=2(x+1)


y+1=2(x+8)


y-8=2(x-1)


y-1=2(x-8)

Answer 1

y - 8 = 2(x - 1)

Explanation:

Slope = (change in y values) / (change in x values)

= (10 - 8) / (2 - 1)

= 2/1

= 2.

equation is y – y1 = m (x – x1), where y1 and x1 are the coordinates of a given point

y - 8 = 2(x - 1)
