Sagot :
Y = 2x + 9
2 is the slope which is rise over run or y2 - y1 over x2 - x1
9 Is the y intercept
2 is the slope which is rise over run or y2 - y1 over x2 - x1
9 Is the y intercept
Answer:
y = -2x + 9
Step-by-step explanation:
So we know that the line is going down, so that means that slope will be negative. Additionally we know that the y-intercept is 9 because that's where the line crosses the y-axis.
To find slope based on the graph, you can start from the left most point and do rise/run until you get to the next point. In this case, you'd start from (0,9) go down 2 units and over to the right 1, so your Slope is -2/1 or just -2.
So it would be written as y = -2x + 9.
