# Slopes and Functions

#12 Determine the slope of each line

Explanation of what I see here:

There is a graph with a line going vertical from Y, 3, 1 and -1

Then there is a line above the numbers: -1, 1, 2, 3, x

A blue line goes between the 3 and 1 (sorry I don't know how to the graph I am looking at)

#22 The Coordinate Formula for Slope

Find the slope of the line that contains each of the following pairs of points.

(-2, -3), (1,3)

#48 Write each equation in standard for using only integers and a positive coefficient for x.

y=1/2x+7

#76 Point Slope Form Find an equation of the line that goes through the given point and has the given slope. Give answer in slope intercept form

Line I goes through (2,-4) and is parallel to the line through (6,2) and (-2,6)

#40 Functions expressed by ordered pairs----Determine whether each relation is a function.

[(1/3,7)(-1/3,7)(1/6,7)]

#88 Function Notation

Let f(x)= 3x -2, g(x) = -x^2 + 3x -2 and h(x) = |x + 2| evaluate each expression

f(1)

If possible, could you copy your graphs in the word document so that I could help you with this problem?
