(0,0),(-1,-3),(7,21)(0,0),(1,3),(7,21)

Explanation:

"to evaluate the y-coordinates substitute the given values"to evaluate the y-coordinates substitute the given values
"of x into "y=3xof x into y=3x

x=0rArry=3xx0=0to(0,0)x=0y=3×0=0(0,0)

x=-1rArry-3xx-1=-3to(-1,-3)x=1y3×1=3(1,3)

x=7rArry=3xx7=21to(7,21)x=7y=3×7=21(7,21)
