Question

Line CD passes through points C(3, –5) and D(6, 0). What is the equation of line CD in standard form?

Answer 1

y =
`(5)/(3) x - 10`

Explanation:

Let's use the slope intercept formula to calculate this.

y=mx + b

-5 = 3m + b

0 = 6m + b

From the last equation, b = -6m

Plugging into the first, -5 = 3m - 6m

So 5 = 3m

m = 5/3

0 = 6*5/3 + b

b = -10

So y =
`(5)/(3) x - 10`
