Question

2x-y+3=0 is a quadratic equatio​

Answer 1

Answer:

no

Step-by-step explanation:

as the power of quadratic equation must be 2

Answer 2

Answer:

Solution:

2x+y+3=0

y=−2x−3

Substitute some values for x and find y

When x=−1,

y=−2×−1−3=2−3=−1

when x=0,

y=−2×0−3=0−3=−3

when x=1,

y=−2×1−3=−2−3=−5

x =−1 ,0 ,1

y =−1 ,−3 ,−5

Plot the graph using the values (−1,−1),(0,−3),and (1,−5) as shown below.
