F x 4 4 6 displaystyle f x4 46 Find the Slope. We can find the b-value the y-intercept by looking at the graph. Substitute the slope for m in the slope intercept form of the equation.
Follow along with these examples to see how to translate linear functions into a graph-friendly format slope intercept form and how to solve for algebra variables using this type of equation.
Solving a linear equation in two variables for y is a type of literal-equation solving. Just type numbers into the boxes below and the calculator will automatically find the slope of two points. A more general way is to use the formula y2 - y1 x2 - x1 where y2 is a result of whatever expression you started with so here 100 dollars for 8 hours which means you could say 100 is one output. 2 1 0 left 210 right 210 and.
