Question

Which equation represents the line passing through the points (1, 1) and (−2, 13)?

Answer 1

find the gradient first then sub in any of the point

Answer 2

4x − y = 5

x − 4y = 5

x + 4y = 5

4x + y = 5

Answer 3

First) find slope:
y - y / x - x
13 - 1= 12
-2 - 1 = -3
slope = 12/3 = 4/1 = 4
Find Point slope form:
y - y = m(x - x)
y - 1 = 4(x - 1)
y - 1 = 4x - 4
+1
y = 4x - 3 in standard form is:

y - 4x = -3

Answer 4
