Parallel line means they have the same slope
y = mx + b
where m = slope
y = -3 + 4
here the slope is negative 3
y = -3x + b
plug in (4, 8)
8 = -3(4) + b
b = 8 + 12
b = 20
The answer is y = -3x + 20
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
It looks like a scalene triangle but i’m not so sure

7-18= a negative number. We know that it'll equal a negative number because the minued(7) is less than the subtrahend(18), which results in a negative number (if both are positive).
We can make an addition problem from this. We can have 18 turn negative and 7 stay positive, and we'll get the same answer.
7+-18=7-18
7-18=7+-18=11
