1. The first equation is - 2x + 5y = 0
Second equation is 
5y = 2x
- 2x + 5y = 0
Hence, the two equations are equivalent.
2. 




Hence, the equations are consistent.
3. 




Hence, the equations are consistent.
4. Equations can be re-arranged as:
x + y - 4 = 0 and
x + y + 6 = 0







Hence, the equations are inconsistent.
5. If we multiply the first equation by 4, we will get,
2y = -4x + 20 which is the second equation.
Hence, the equations are equivalent.
Answer:
1/20
Step-by-step explanation:
(1/4)/5= (1/4)/(5/1)
You cross multiply and you get 1/20
In this item, we are given with the slope, m = 2/3 and intercept of (1,1). The equation of the line that contains these properties is,
y - y₁ = m(x - x₁)
Substituting the known values,
y - 1 = (2/3)(x - 1)
Simplifying,
3y - 3 = 2x - 2
Further simplifying,
<em> 2x - 3y = -1</em>
Consider this solution.
