rounding to the nearest tenth will be 20
M + b = 67
b = 4m - 8
m + 4m - 8 = 67
5m - 8 = 67
5m = 67 + 8
5m = 75
m = 75/5
m = 15 <=== Maggie's age
b = 4m - 8
b = 4(15) - 8
b = 60 - 8
b = 52.....her brother is 52
Answer:
I would say too broad.
Step-by-step explanation:
Given point (2,8) and slope, we can use slope intercept form.
y-y1=m(x-x1)
y-8=-2(x-2)
y-8=-2x+4
y=-2x+12
Where, y=mx+b, b is the y intercept.
In this case, the intercept is 12.
