For the equation of the line of the form y = mx + b, m is the slope of the line and b is the y-intercept which is the value of y when x is equal to zero. The slope is the rate of change of y per change in x. "y" would represent the dependent variable which is the weight of the baby while "x" represents the independent variable which is the number of months or the age of the baby in months. We calculate the slope as follows:
slope = (11 - 9) / ( 4 - 0) = 2/4 = 0.5
at x = 0, it is said that the weight of the baby is 9 lbs so the value of b would be 9.
The equation of the line would be y = 0.5x + 9
Answer:
Step-by-step explanation:
This is a compound inequality that basically states that the X value is greater than or equal to -5, but less than or equal to -1. It is inclusive, because it includes both numbers and therefore should have an equal to sign () instead of just less than or greater than ( < or >).
Answer:
Step-by-step explanation:
Answer:I think it is y= 25X + 200 or it is y=25x- 200
Step-by-step explanation:
Simply just think of two numbers that multiply to -48.
That's -12 and 4.
Does it add up to 8: -12 + 4 = 4 -12 = -8
It doesn't, so we revert the sign.
12 and -4 Product = 12*-4 = -48
Addition = 12 + -4 = 12 -8 = 8. Correct.
The answer is 12 and -4.
