Write the equation of a line in slope-intercept form that goes through the points (1, 1)and (−1,−9

y = 5x - 4

Step-by-step explanation:

The line goes through the points (−1,−9) and (1, 1).

We can see quickly that x increases by 2 and y increases by 10.  Thus, the slope of this line is

m = rise / run = 10 / 2 = 5.

Using the slope-intercept equation for a straight line, y = mx + b, we get

1 = 5(1) + b.  Thus, b = -4, and the desired equation is

y = 5x - 4

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.
