Answer:

Step-by-step explanation:
The equation of a line is:

Where m is the gradient (or as you call it, the slope), and c is the y-intercept. We already know what the slope is, therefore we need to find the y-intercept. You have been given the coordinates (-6, 2), but to find the y-intercept, X must be equal to 0. Since the gradient is 1, we know that for every value we add to X, we must add the same to y. To get from -6 to 0, we must add 6, so we must do the same 2, leaving our y-intercept coordinates as (0, 8), and our y-intercept as 8. Plugging in our values, we are left with the following equation:

Answer:
This is the answer of your question.
6x+25=10x-47 by corresponding angles.
72=4x
x=18
The unit rate is 6.4 yards per second.
Step-by-step explanation:
Given statement is;
400 yards in 62.5 seconds
As we have to find unit rate in terms of seconds; therefore, we will divide total yards by total seconds.
62.5 seconds = 400 yards
Dividing both sides by 62.5

The unit rate is 6.4 yards per second.
