4.3x(3.9 - 8.5) + 2.3y(-6.2 - 9.1)......when x = -2.1 and y = 3.5
4.3x(-4.6) + 2.3y(-15.3)
4.3(-2.1)(-4.6) + 2.3(3.5)(-15.3)
-9.03(-4.6) + 8.05(-15.3)
41.538 - 123.165
-81.627 <===
Answer:
y=9.75x+60
Step-by-step explanation:
We want our equation to look like y=mx+b
Let's start out by calculating the slope
we have
y=9.75x+b
we know that when x= 3 y= 89.25
89.25=9.75(3)+b
solve for b = 60
It is not continuous at x=3
