Would it be more convenient to use substitution, elimination by adding or elimination by subtracting for the following two systems of equations? 1: 3x-2y=0 , 4x+2y=14 2: 6x-2y=18 , 6x+7y=12

As a general rule: if you find two opposite coefficients for the same variable, it is convenient to add. If you find two equal coefficients for the same variable, it is convenient to subtract.

In the first system, the coefficients of are -2 and +2. If you add those you get 0, and thus you eliminate the variable.

In the second system, the coefficient of is 6 in both equation. If you subtract those you get 0, and thus you eliminate the variable.

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

cool? what is the actuall ?
