y=3x+19

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=3

b=19

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

Slope: 3

y-intercept: 19

Slope: 3

y-intercept: 19

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

Replace the variable x with 0 in the expression.

f(0)=3(0)+19

Simplify the result.

Multiply 3 by 0.

f(0)=0+19

Add 0 and 19.

f(0)=19

The final answer is 19.

19

The y value at x=0 is 19.

y=19

y=19

Choose 1 to substitute in for x to find the ordered pair.

Replace the variable x with 1 in the expression.

f(1)=3(1)+19

Simplify the result.

Multiply 3 by 1.

f(1)=3+19

Add 3 and 19.

f(1)=22

The final answer is 22.
