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=13
b=-19
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 13
y-intercept: -19
Slope: 13
y-intercept: -19
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.

Multiply 13 by 1.
f(1)=13-19
Subtract 19 from 13.
f(1)=-6
The final answer is -6.
