Answer:
y = 3.75x+5
Step-by-step explanation:
*** some of your points might be wrong ***
1. Take two points on the line. Ex: (0, 5) and (4, 20)
2. Find the slope using the change in y divided by the change in x.
Ex: m=(20 - 5)/(4 - 0) = 15/4 -> m= 3.75
3. Look at the graph for the y-intercept (when x =0)
y -intercept -> b = 5
Check:
y = mx + b; m = 3.75 (4, 20) -> x= 4 and y =20
20 = 3.75(4) + b
20 = 15 + b
5 = b
4. plug in to slope-intercept form: y = mx +b
y = 3.75x+5
