Identify the graphed linear equation.
alukav5142 [94]

Answer:

C

Step-by-step explanation:

to find the value of the constant at the end of the equation, look for where the line meets the y-axis (here it is +1). Since all of the answer choices have 4 as a slope, looking to see if the line is going down or up will tell you if it's -4 or +4. (here it is negative)
