Step-by-step explanation:
Answer:
1) The straight line on the graph below intercepts the two coordinate axes. The point where the line crosses the x-axis is called the [x-intercept]. The [y-intercept] is the point where the line crosses the y-axis. Notice that the y-intercept occurs where x = 0, and the x-intercept occurs where y = 0.
2) There's another important value associated with graphing a line on the coordinate plane. It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." ... This point will always have an x coordinate of zero.

Answer:
Y=1.25x+3.50
Step-by-step explanation:
The problem is linear so it uses y=ax+b form. In this we can set the left group as x and the right group as y. Then use
(y2-y1) / (x2-x1) to find the slope. once the slope is found (1.25) we can find the y intercept by using one of our coordinates with our equation y-ax=b
12.25-1.25*7=b
b=3.5
now we put them all together to make
Y=1.25x+3.50
The options are missing, so i have attached it.
Answer:
Measurement unit for F = (Nutrients • Moisture)/Pollutants.
Option C is correct
Step-by-step explanation:
From the question, we are given the formula; F = NM/P
where;
N is the amount of nutrients in the soil
M is the amount of moisture in the soil.
P is the amount of pollutants in the soil
From the definition of the terms above, the units of the can be expressed as;
N = nutrients
M = moisture
P = pollutants
Thus, the measurement unit for fertility is;
F = NM/P = (Nutrients • Moisture)/Pollutants
