Answer:
y = 5x + 3
Step-by-step explanation:
Slope-intercept form is y=mx+b (where m is the slope and b is the y-intercept)
First find the slope with (13-8)/(2-1) = 5
Plug the slope and one of the coordinates into the equation to find the y-intercept now:
13 = 5 * 2 + b
13 = 10 + b
b = 3 (y-intercept is 3)
Now, write final equation: y = 5x + 3
