The ratio is the relationship of two numbers. Here is an example, you have 2 apples and 6 bananas. To compare the ratio between the apples and the bananas we create a ratio, so the ratio would be 2 to 6, or 2:6, or 2/6.
A rate is a little different than the ratio, it is a special kind of ratio. That is a comparison of measurements that have different units, like pounds and quarters.

Answer:
see below
Step-by-step explanation:
y= 1/2x - 2
To find the x intercept, set y =0 and solve for x
0= 1/2x - 2
Add 2 to each side
2 = 1/2x -2+2
2 = 1/2x
Multiply by 2
2*2 = 1/2x *2
4 =x
The x intercept is 4
