Answer:
We need more information, but the equation is y=(slope)x+(y-intercept). If you can find two points on the line, and the y-intercept, you've got your equation.
Explanation:
To find the slope, you need two points. Then you take the y-value of the second point minus the y-value of the first point and divide that by the x-value of the second point minus the x-value of the first. If the y-intercept is not given, you need to plug in the equation, making x=0, and then solve for b, also known as the y-intercept. Hope this helps! Feel free to let me know if this is not clear.
