Question

Identify the graphed linear equation.

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

Answer 1

y = - 4x + 1 → C

the equation of the line in ' slope-intercept form ' is

y = mx + c ( m is the slope and c the y-intercept )

from the graph c = 1

using the points ( 0 , 1 ) and (1 , - 3 )

m = (- 3 - 1 )/( 1 - 0) = (- 4 )/1 = -4

equation is y = - 4x + 1

Answer 2

the answer would be c
