Dividing two negative values results in a positive value.
y=13+-x-3
Dividing two negative values results in a positive value.
y=13+x3
y=13+x3
y=13+x3
y=13+x3
Rewrite in slope-intercept form.
Tap for more steps…
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Reorder 13 and x3.
y=x3+13
Rewrite in slope-intercept form.
y=13x+13
y=13x+13
Use the slope-intercept form to find the slope and y-intercept.
Tap for more steps…
Find the values of m and b using the form y=mx+b.
m=13
b=13
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 13
y-intercept: 13
Slope: 13
y-intercept: 13
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 2 to substitute in for x to find the ordered pair.
Tap for more steps…
Replace the variable x with 2 in the expression.
f(2)=23+13
Simplify the result.
Tap for more steps…
Combine the numerators over the common denominator.
f(2)=2+13
Add 2 and 1.
f(2)=33
Divide 3 by 3.
f(2)=1
The final answer is 1.
