Step-by-step explanation: Slope-Intercept equations and graphs.
These are in y = mx + b form. M is slope. b is the y-intercept
For the y-intercept, you identify and label the place on the y-axis where the graphed line crosses it. That is one HINT to figuring out the equation that matches the graph. If the y-intercept is 0, there will be nothing after the 'x' term. If the y intercept ia any other number, that number will appear as a + or - after the 'x' term when you simplify the equation in y = mx + b form.
You have to draw the "stair steps" It helps you see slope. How many blocks up or down is the Rise. How many blocks from left to right is the Run.
Start by making a fraction Rise/Run if the Run is 1, the Slope is a whole number, the Numerator of the fraction (the 1 disappears from the equation).
