Answer:
Step-by-step explanation:
1+12=30
X intercept is (-250,0) and y intercept is (0,100). Intercepts are where a line crosses the x axis and y axis.
The equation would be 400+20c per week so if you do that equation, to figure it out 680-400=280 and then you would divide it by 20 and whatever that answer is, in this case it would be 14.
We can say at month 0 she was 43 inches tall.
And at month 18 she was 52 inches tall.
We can say that x is the number of months and y is her height.
Rise/run
y2-y1/x2-x1
52-43/18-0
9/18
1/2
So the slope is 1/2 (which is what you are looking for.) and if you were to write an equation it would be y=1/2x+43

Answer:
(y - 18) = -3/2 (x - 12)
Step-by-step explanation:
125% of 12 equals 15
75% of 18 equals 13 1/2
so the slope equals 4.5/-3 or -3/2
