Hope this helps!=)
Guys help me I’m stuck in this question also it’s in my homework
For example: 18-inch princess necklace made with 4mm beads: 18 x 25.4 ÷ 4 = 114.3. 32-inch opera necklace made with 10mm beads: 32 x 25.4 ÷ 10 = 81.2.
Necklace?
Type Length
Collar 14 to 17 inches
Choker 16 to 18 inches
Princess 17 to 19 inches
Matinee 20 to 25 inches
<u>Solution</u>:
3y = -9x - 22
y = -3x - 22/3
The graph parallel to this graph (9x + 3y = -22) should have a gradient of -3
In the choices above i.e A,B,C & D there is not a single equation with a gradient equal to -3.
