No

That is because you would plug the x in for the x and the y in for the y. Once you plug them in for the first one it would be...

3(1)+4(4)=19
3+16=19
19=19

But when you do the second one it will not work.

1+14(4)=15
57≠15

Answer:  The answer would be letter A

slope (m)=-9/2

intercept on x-axis=56/9

intercept on y-axis=28

Explanation:

18x+4y=112

(18x)/112+(4y)/112=1

(x/1)/(56/9)+y/28=1

intercept on x-axis=56/9

intercept on y-axis=28

now, 4y=-18x+112

y=-9/2x+28

so, slope (m)=-9/2

Step-by-step explanation:

Move all terms that don't contain  y  to the right side and solve.

y =  28  −  (9 x) /(2)
