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:

Answer:
mode : the value that appears most frequently in a data set
mean : te everage of all number
median : the middle number in a sorted, ascending or descending
range : the difference between the largest and smallest numbers.
ANSWER ;
mode : none
mean : 145.4 ( you need to add all the number and divide by how many your family member)
median : 159
range : 80 ( the largest - the smallest)
Because completementary angles add up to 180 degrees (angle 3 and angle 4)
and interior angles of a triangle will also add up to 180 degrees
if you compare these two facts, then angle 4 equals the 2 non adjacent interior angles
