Solve equation by factoring.
X3 - 49x = 0

Answer:
x = - 7, x = 0, x = 7
Step-by-step explanation:
Given
x³ - 49x = 0 ← factor out x from each term
x(x² - 49) = 0 ← x² - 49 is a difference of squares, thus
x(x - 7)(x + 7) = 0
Equate each factor to zero and solve for x
x = 0
x - 7 = 0 ⇒ x = 7
x + 7 = 0 ⇒ x = - 7
Answer: x=7 or x=-7
x(x+7)(x-7)=0

ANSWER
See attachment.
EXPLANATION
The given equation is
-3y=5x-7
when y=0,
-3(0)=5x-7
0=5x-7
5x=7
we plot (7/5,0)
when x=0
-3y=5(0)-7
y=7/3
we plot (0,7/3)
when x=1,
-3y=5(1)-7
-3y=-2
y=2/3
we plot (1,2/3)
