Make sure that its correct ; ) really appreciated. can you explain to me because i dont just want the answers i wanna learn

Hello!

Slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line intersects the y-axis).

To write the equation of the graph, first find slope. You can find slope by calculating the change in y-values divided by the change in x-values using the formula:



Your values for  and  will use the coordinates plotted on the graph--(2, 6) and (-4, -6). Plug them in and solve to get slope.






The slope of the line is 2.

As you can see, the graph intersects the y-axis at (0, 2); that is your y-intercept. You now have all the information you need to write the equation of the graph in slope-intercept form:

y = mx + b
y = 2x + 2

To calculate the slope of the second graph, repeat the steps above for solving for slope using coordinates.






The slope of the second line is .

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable
