Question

Help me with this please

Answer 1

Step-by-step explanation

A(4,1)
B(2,9)

m= Y2-y1/x2-X1
= 9-1/2-4 = 8/-2=-4

y=mx+b m=decline

Y=-4x+b —> replacing by point A(4,1)
1=-4x4+b
1=-16+b
b=17

Y=-4x+17 ✔️

Answer 2

Explanation:

y = -4x + 17

=> (4,1)

x=4 --> y = -4(4)+17=-16+17=1

(4,1) matched

=> (2,9)

x=2 --> y=-4(2)+17=-8+17=9

(2,9) matched
