Answer:
A. y = -2x + 2 B. y = x - 1
Step-by-step explanation:
A.
We have two given points, which are (0, 2) and (1, 0). Because one of the given points has the x-coordinate 0, it means it is the y-intercept. The y-intercept is 2, which means that 2 is the B of our equation. Now, I will use the skeleton method to find the slope.
((2) - (0))/((0) - (1)) = -2
Now we know that -2 is the slope, so we can form the equation.
y = -2x + 2
B.
The line shown in exercise B is actually a 1x equation since it is seen that it goes through every whole number without forming decimals. So our m is 1. The y-intercept, which can be seen by looking at the y-coordinate at x = 0, is -1. So -1 is our B.
The equation is as follows.
y = x - 1

The value of y when x =7 according to the task content is; y = 7/25.
<h3>What is the value of y when x = 7 given that y varies directly with x?</h3>
As indicated by the relationship between x and y in the task content, since y varies directly with x; then the required value of y can be determined as;
5/(1/5) = 7/y
25y = 7
y = 7/25.
Ultimately, the value of y when x =7 according to the task content is; y = 7/25.
