Answer:
y=5
Step-by-step explanation:
First, write your current equation. Y=0x+b. Next, subsitute the x and y for the coordinates (2,5) to find the y-intercept. It should look like this: 5=0(2)+b. 2 times 0 equals 0, so you have 5=b, which means 5 is your y-intercept. Now, go back to the original equation Y=0x+b and replace the b with 5. However, since the slope is 0, that means it will be a horizontal line. So, you can just write it as y=5.
