What information can you learn from the slope-intercept form of the linear function?

Practice makes perfect

We want to graph the given linear function. Let's recall the functions written in slope-intercept form follow a specific format. f(x)= mx+ b In this form, m represents the slope of the line and b represents the y-intercept. Let's highlight them in the given function. f(x) = x-8 ⇔ f(x)= 1x+ ( - 8) The slope is 1. It means that for every 1 unit we move in the positive horizontal direction, we move 1 unit in the positive vertical direction. m= 1/1 ⇔ rise/run=1/1 The y-intercept is - 8, so the graph crosses the y-axis at the point (0, - 8). To graph the function, we will plot the y-intercept and then use the slope to find another point on the line.
