# Graph -1-9 square root of 8

-1-98
Use the slope-intercept form to find the slope and y-intercept.
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Find the values of m and b using the form y=mx+b.
m=-1
b=-182
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: -1
y-intercept: -182
Slope: -1
y-intercept: -182
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
Choose 0 to substitute in for x to find the ordered pair.
Replace the variable y with 0 in the expression.
-1-18⋅0=-1-182
-1-182
The first point is (0,-1-182).
(0,-1-182)
(0,-1-182)
Choose 1 to substitute in for x to find the ordered pair.
Replace the variable y with 1 in the expression.
-1-18⋅1=-1-182
-1-182
The second point is (1,-1-182).
(1,-1-182)
(1,-1-182)
Create a table of the x and y values.
