Yes, so start by solving for y by subtracting everything else to the opposite side of the = from y.
1. y = 5 - x
2. y = x - 1
Now that we have our two equations in point-slope form, we can create graphs.
Our point-slope form is y = mx + b where m = slope of line and b = y-intercept.
The slope of equation 1. is -1 and the slope of equation 2. is 1
The y-intercept (how much the line goes up or down on the y-axis) for equation 1. is 5 and the y-intercept of equation 2. is -1
x is the variable
<em>In mathematics, a variable is a symbol; in this case, X.</em>
The volume of the car is 1800cm^3 which is equivalent to 0.0018m^3
<h3>Scale modelling</h3>
Given the scale factor that model of a car is amde to a scale of 1:40, Giving that the model as 45cm^3, this means that;
1 = 45cm^2
Determine the volume of the car
40 = x
Find the ratio
1/40 = 45/x
x = 40*45
x = 1800cm^3
x = 0.0018m^3
Hence the volume of the car is 1800cm^3 which is equivalent to 0.0018m^3

Answer: A and B only
Step-by-step explanation:
In function, for one value of x there must be only one value of y.
The sum of two supplementary angles is 180 degrees.
A+B=180.
80+B=180
B= 180-80
B=100
