Graph g(x)=1/2x+3

Math
g(x)=12x+3
Rewrite the function as an equation.
y=x2+3
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=12
b=3
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 12
y-intercept: 3
Slope: 12
y-intercept: 3
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.

Replace the variable x with 0 in the expression.
f(0)=02+3
Simplify the result.
Tap for more steps…
Divide 0 by 2.
f(0)=0+3
Add 0 and 3.
f(0)=3
The final answer is 3.
