Suppose a system of two linear equations has one solution. what must be true about the graphs of the two equations?
)they intersect at one point,
)they intersect at two points.
)they have the same slope.
)they have the same y-intercept.
!

They intersect at one point.

Step-by-step explanation:

If a system of two linear equations has one solution then the two lines intersect at one point. The solution is the point of intersection.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
