y=mx+b is the standard function for any straight line
y and x are constants, so they never change in the final form
m is the slope, which is given
b is the y intercept, which is not given
we have to plug in the values to find the solution, so plug in the (x,y) coordinates for their respective places in the equation
-8 = (-3/5)(-3) + b
-8 = 1.8 + b
-9.8 = b
now that we have b, we can just put the slope back in for m and get the answer
y= -3/5x -9.8

Step-by-step explanation:
- -3a²-b³+3c²-2b³
- -3(2)²-(-1)³+3(3)²-2(-1)³
- -3(4)-(-1)+3(9)-2(-1)
- -12+1+27+2
- -11+27+2
- 16+2
- 18
Answer:
x > 23
Step-by-step explanation:
5x – 1 < 7x - 47
Add 1 to -47, you get -46.
5x < 7x - 46
Subtract 7x from 5x.
-2x < -46
Multiply both sides to reverse the inequality.
2x > 46
Divide both sides by 2.
x > 23
