2x-3/4=1/2
The answer is X=5/8
Answer:
Step-by-step explanation:
<u>Method 1</u>
convert the fractions so that their denominators are 12:
From inspection, we can determine that the fraction that lies exactly halfway between and is
<u>Method 2</u>
Find the difference between the fractions and divide by 2:
Add this to the smallest fraction (1/2):
The answer is the second one
In the form y = mx + c
First thing's first, we can determine the gradient, m, simply by looking at the points.
The gradient is determined by how much the value of y increments (or decrements) for each increase of 1 on the x axis.
Every time x increases by 1, y decreases by 4, meaning our gradient is -4.
We are also able to determine our constant, c, by seeing where our line will cross the y axis. In this case, there is a point dead-on the y axis at (0, -2), meaning our constant is -2.
With this information, we can put together the linear equation, y = -4x -2.
