Functions and linear equations III If we in the following equation y=x+7 assigns a value to x, the equation will give us a value for y. Example y=x+7 ifx=2then y=2+7=9 If we would have assigned a different value for x, the equation would have given us another value for y. ...

Change f(x) into a variable other than x, and then it is an equation. Linear function equations can be in many different forms, including: Slope-intercept form: y = mx + b (the typical form for linear functions) Point-slope form: {eq}y-y_1=m(x-x_1) {/eq} General form: Ax ...
