Answer:
The equation in slope-intercept form of required line is: 
Step-by-step explanation:
We need to write equation in slope-intercept form to represent the line on the graph.
The general equation in slope-intercept form is: 
Where m is slope and b is y-intercept
Finding slope using formula: 
Looking at he graph we have
Putting values in formula and finding slope:
So, we get slope m = 2/3
Using slope m=2/3 and point (3,-4) we can find y-intercept
So, y-intercept b = -6
The equation of line having m=2/3 and b=-6 will be:
The equation in slope-intercept form of required line is:

Answer:
The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.
Step-by-step explanation:
When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.
If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.

Even without doing the math, (and without having the requisite diagram to view), it seems likely that the rectangle was simply divided along the diagonal. And, if that's the case then the two triangles formed would have the same area. So, if one triangle's area ABC is 600 sq. yds. as the problem states, then the other triangle ACD also would be 600 sq. yds.
But if we do the math anyway, we can get the same result.
Keep in mind that:
P of rectangle = 2 ( l + w)
A of rectangle = (l x w)
A of triangle = h x b divided by 2
I'd say that the length of the rectangle is 40 and the width is 30.
P of rectangle is 2 (30 + 40) = 140 .... check
A of rectangle is 30 x 40 = 1,200 .... check
A of triangle is 30 x 40 divided by 2 = 600 ...... check
