Answer:
y = 2x + 5
Step-by-step explanation:
In order to write this equation (in slope-intercept form), you need to find the slope (m) and the y-intercept (b) so that you can plug them into the following linear equation:
y = mx + b
First, you need to find the slope. You can do this by taking two points on the graph and doing (change in y/change in x):
using (5, 15) and (10, 25),
(25 - 15) / (10 - 5)
= 10/5
= 2
so m = 2
Now, you need to find the y-intercept. Since a graph is provided, you just need to look at the y-intercept, which is 5, so b = 5.
Finally, you just need to put it all together:
y = mx + b, where m= 2 and b = 5,
y = 2x + 5
