y=52x-1

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=52

b=-1

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: 52

y-intercept: -1

Slope: 52

y-intercept: -1

Choose 0 to substitute in for x to find the ordered pair.

Replace the variable x with 0 in the expression.

f(0)=5(0)2-1

Simplify the result.

Multiply 5 by 0.

f(0)=02-1

Divide 0 by 2.

f(0)=0-1

Subtract 1 from 0.

f(0)=-1

The final answer is -1.

-1

-1

The y value at x=0 is -1.

y=-1

y=-1

Choose 2 to substitute in for x to find the ordered pair.

Replace the variable x with 2 in the expression.

f(2)=5(2)2-1

Simplify the result.

Multiply 5 by 2.

f(2)=102-1

Divide 10 by 2.

f(2)=5-1

Subtract 1 from 5.

f(2)=4

The final answer is 4.
