Aline passes through the point ( 4, 19 ) and ( 9, 24 ) write a liner function in the form y=mx + b for this line.

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

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
