Question

Identify the graphed linear equation.

A) y = 4x + 1
B) y = 4x - 1
C) y = -4x + 1
D) y = -4x - 1

Answer 1

The answer to your question is letter C

Explanation:

Process

1.- Find two points of the line

A ( 0, 1)

B ( 1, -3)

2.- Find the slope of the line

`m = (y2 - y1)/(x2 - x1)`

`m = (-3 - 1)/(1 - 0)`

`m = (-4)/(1)`

m = -4

3.- Find the equation of the line

y - y1 = m (x - x1)

y - 1 = -4( x - 0)

y -1 = -4x

y = -4x + 1
