Question

PLS HELP ME WITH THIS I BEG

Answer 1

y=-3x-1

Step-by-step explanation:

We khow the the equation of the graph function have this form : y=mx+c

• Let f be our function
• m= (f(1)-f(-1)]/[1-(-1)]=(-4-2)/2= -3
• so y= -3x+c
• let's replace x and y by the coordinates of a khown point to calculate c

• (1, -4) ⇒ -4= -3*1+c ⇒ c= -4+3 ⇒ c= -1
• y= -3x-1
