Question

The graph of a line passes through the points (0, 5) and (-10, 0). What is the equation of the line?

Answer 1

(0,5)(-10,0)
slope = (0 - 5) / (-10 - 0) = -5/-10 = 1/2

y = mx + b
slope(m) = 1/2
use either of ur points (0,5)...x = 0 and y = 5
now we sub and find b, the y int
5 = 1/2(0) + b
5 = b

so ur equation is : y = 1/2x + 5
