Answer:

Step-by-step explanation:
First to write this equation you will need to know <em>slope intercept form</em> which is the equation that the people that wrote this problem are presumably looking for. Slope intercept form can be simply written as
. The variable
would be the slope while the variable
would be the y -intercept.
So to find out this we would have to assume that m or the slope would have to be 1 so we would have
or
.
Now we have the first half of the equation we can move on to the variable
or the y-intercept (0,-6) . To find the variable
we will just have to graph the point (0,-6) which as you can see from the picture is the y-intercept and that is -6 units below 0. So the final answer will be 
Answer:
I believe it is Option 1
Step-by-step explanation:
Since the fourth root of 81 will be 3 and of 16 will be 2.
A. 18 - 25 because 29% plus 23% equals 52%
Divide the speed value by 1.609,
1kilometer per hr=0.621mph
80kph=49.7097Mph
