Answer:
y=2x-1
Step-by-step explanation:
straight line equation
y=mx + c
find gradient(m) first,use formula;
m=3-7/2-4
m= -4/-2
m=2
use one the coordinates
(2,3)
3=2(2)+c
3=4+c
c=3-4
c = -1
y = 2x - 1
so it says 6 times as old as June
so that would be 6x
then it said the sum so that's addition is no less than so that's subtraction
so it would be
X because we June's father age
so x times 6 > 77
