Equation:
y - 10 = -5x
Solve:
(y - 10) + 10 = (-5x) + 10
y = -5x + 10
Remember the formula (Slope Intercept Form):
y = mx + b
m = Slope (Rise/Run)
b = Y-intercept
So your graph would look something like the attached image:

My "work" is to enter the equations into a graphing calculator and let it show me the answers--just as your "work" is to copy the question to Brainly.
The solutions are
(x, y) = (-0.5, 7.5)
(x, y) = (3, 25)
_____
When you equate the expressions for y, you get the quadratic
2x² -5x -3 = 0
(2x +1)(x -3) = 0
x = -1/2 or 3
y = 5(x +2) = 15/2 or 25
Answer:
Step-by-step explanation:
density is mass divided by volume, so 25g divided by 10 cm = 2.5 g
