Since you have points (-2,7) you can plug those into each equation to see if they work. If the equation works your answer should be equal to y. in doing that the correct equation is
(B) y=-x+5
y=-x+5
7=-(-2)+=
7=7
6/4; sum the digits and divide by the number of digits used
Answer:
The age of Sue could be 7 years
Step-by-step explanation:
Jenny is 8 years older than twice her cousin Sue's age.
The first equation will be :
J = 8 + 2S ---------(1)
The sum of their ages is less than 32.
The second equation will be :
J + S < 32 ----------------(2)
Now rearrange both equations :
8 + 2S + S < 32
3S < 32 - 8
3S < 24
S < 24/3
S < 8
S = 7
The age of Sue could be 7 years.
The slope of the line is 1/3
