Answer:13
Step-by-step explanation:
2(7)-3
Y = mx + b
slope(m) = -5/2
(-4,4)...x = -4 and y = 4
now we sub and find b, the y int
4 = -5/2(-4) + b
4 = 10 + b
4 - 10 = b
-6 = b
so ur equation is : y = -5/2x - 6....or 5x + 2y = -12
Basically set up two rows divided into however many section you need. Row 1 is the x values, Row 2 is the y values
This would equal 3/2 or 1.5.
Hope this helps!
