Answer: y = -1x
Step-by-step explanation: The equation can be determined using the equation y=mx+b, where "y" represents the output, "m" represents the slope (vertical change compared to the horizontal change), "x" represents the input, and "b" represents the y-intercept (where the line crosses the y-axis). Since the slope (rise over run) is -1/1 (or just -1) and the y-intercept is (0,0), the equation of the line is y = -1x because you can disregard the "b" value of 0 since it has no affect on the graph since it holds no value.
Answer:
The equation is y = 1x
Step-by-step explanation:
Use the formula to find the equation.
The formula is y = mx + b
m is the slope
b is the y-intercept
Since the origin is at (0,0). The y-intercept is 0
To find the slope use the formula: m = (y2 - y1)/(x2 - x1)
You can plug in any coordinate that is in the graph. For example:
(1, 1) and (2, 2) Note: These coordinates are in the graph.
m = (2 - 1)/(2 - 1) = 1/1 = 1
so the slope is m = 1.
Therefore, the equation is y = 1x + 0 or y = 1x
