Answer:
Step-by-step explanation:
alright! let's do it
y =mx + b
the slop would be "m"
y = 4x+b
and then, let's plot -2 to x and 4 to y.
why? well to find " b " as y intercept
4 = 4(-2) +b
4 = -8 +b
+8 +8 both side add 8 to keep the same between 2 sides
12 = b
so:
y = 4x +12
and done! hope you enjoy!
y = 2m-5
Kim's age now is y = 2m-5
Let m represent martas age now and y represent Kim's age now
Given;
Five years ago Kim's age was twice as great as martas age.
(y-5) = 2(m-5)
Solving for y;
y-5 = 2m-10
y = 2m-10+5
