Answer:
y = x + 15
Step-by-step explanation:
(4,19)...x1 = 4 and y1 = 19
(9,24)...x1 = 9 and y1 = 24
slope(m) = (y2 - y1) / (x2 - x1) = (24 - 19) / (9 - 4) = 5/5 = 1
y = mx + b
slope(m) = 1
use either of ur points...I will use (4,19)...x = 4 and y = 19
now we sub and find b, the y int
19 = 1(4) + b
19 = 4 + b
19 - 4 = b
15 = b
so ur equation is : y = x + 15
