**Step-by-step explanation:**

So, we have to find the slope of the line. We are given two points, so we can use those:

(x1,y1) = (-4,6)

(x2,y2) = (1,2)

m = (y2-y1)/(x2-x1) = (2-6)/(1--4) = (2-6)/(1+4) = -4/5

Also, we know that point-slope is of the form:

(y-y1) = m*(x-x1)

It doesn't matter which point you use, though, you can also use:

(y-y2) = m*(x-x2)

So we can plug the variables into the equation and get:

(y-2) = -4/5*(x-1)

OR

(y-6) = -4/5*(x+4)

Let h be high temperature for today.

We are told that today high temperature will be at least 75 degrees. This means the high temperature will be greater than or equal to 75 degrees.

Let us represent this information by our inequality.

**Therefore, our desired inequality will be . **
