1) Find the graph of a line passing through (-1, 4) and (2, 0).
The slope of two points can be determined by dividing the difference of y-values by the difference of x-values:

The slope of this equation is -4/3. Inputting this into the slope-intercept form of an equation, we get:

To find b, substitute x and y for one of the given coordinate pairs:
0 = (-4/3)(2) + b
0 = -8/3 + b
8/3 = b
Substitute the b value into the equation to finish the line:

Yes I sure did hang the picture what about it
Let X= # of days, y= finial cost. Part A= 12+7x=y. Part B= 12+7(18)= $138. Part c= 12+7(187)= $1,321
