A line passes through the points (4, 19) and (9, 24). Write A linear function in the form Y equals MX plus be for this line.
avanturin [10]

Answer:

y = x + 15

Step-by-step explanation:

okay so you're gonna use the y2-y1/x2-x1 formula to find the slope (m)

24 - 19/9 - 4 = 5/5 = 1

so that is your slope (m)

and now if you follow your slope then you should get your y-intercept (b)

4 - 1 = 3      19 - 1 = 18

(3, 18)

3 - 1 = 2      18 - 1 = 17

(2, 17)

2 - 1 = 1       17 - 1 = 16

(1, 16)

1 - 1 = 0       16 - 1 = 15

(0, 15)

so thats your y-intercept (b)

and the equation will look like:

y = mx + b          y = x + 15  or    y = 1x + 15 (but the 1 isn't necessary)
