M=0.25 so the answer is a
Answer:
Obtuse angle
Step-by-step explanation:
Answer:
Bren=5 years
Tom=7yrs
Sally=4 yrs
Kate=8years
Step-by-step explanation:
-Let Bren's current age be x, therefore Tom is x+2
-Let Sally's current age be y, therefore Kate is 2y
-Also, given that:

#We calculate the ages one year ago of Tom and Sally:

#Substitute for x in i;

Composite because it can be divided by many numbers
the slope intercept form is y=mx+b
since the line intersects at (0,3) b= 3
since the slope is 0 m= 0
so the equation would be y=0x+3 or y=3
