# Graph y/2=x-1 y2=x-1
Solve for y.
Multiply both sides of the equation by 2.
2⋅y2=2⋅(x-1)
Simplify both sides of the equation.
Cancel the common factor of 2.
Cancel the common factor.
2⋅y2=2⋅(x-1)
Rewrite the expression.
y=2⋅(x-1)
y=2⋅(x-1)
Simplify 2⋅(x-1).
Apply the distributive property.
y=2x+2⋅-1
Multiply 2 by -1.
y=2x-2
y=2x-2
y=2x-2
y=2x-2
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=2
b=-2
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 2
y-intercept: -2
Slope: 2
y-intercept: -2
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 1 to substitute in for x to find the ordered pair.
Replace the variable x with 1 in the expression.
f(1)=2(1)-2
Simplify the result.
Multiply 2 by 1.
f(1)=2-2
Subtract 2 from 2.
f(1)=0
The final answer is 0.
0
0
The y value at x=1 is 0.
y=0
y=0
Choose 0 to substitute in for x to find the ordered pair.
Replace the variable x with 0 in the expression.
f(0)=2(0)-2
Simplify the result.
Multiply 2 by 0.
f(0)=0-2
Subtract 2 from 0.
f(0)=-2
The final answer is -2.
-2
-2
The y value at x=0 is -2.
y=-2
y=-2
