Y = -4/5 + 7, the 7 is the slope intercept and the -4/5 is the slope

For this case, the first thing you should do is write the generic equation of the line.
We have then:
y-yo = m (x-xo)
The slope of the line will be:
m = -4 / 5
The ordered pair is:
(xo, yo) = (0, 7)
Substituting the values:
y-7 = (- 4/5) * (x-0)
Rewriting:
y = (- 4/5) x + 7
Answer:
An equation in slope-intercept for the line that has a slope of -4/5 and passes through (0,7) is:
y = (- 4/5) x + 7

Well all you need to do to write the linear equation for this function. I assume you want to know, is that you must obtain 2 points, and calculate the slope, then place the info within the following form.

Y = mx + b
1 of the points has to be the y intercept, which can be obtained from the graph, and the other, any other point, which can also be the X intercept.

So, X intercept - (2,0)
Y intercept - (0,3).

Slope = y/X = 3-0/0-2
Slope = 3/-2 or -3/2.

Now put everything together in form:

Y = mx + b

Y = -3/2x + 3.

I believe this is the solution.
