Question

4.

Find the slope and y-intercept of the line.

18x + 4y = 112

A.
`-(9)/(2)`; 28

B.
`-(2)/(9)`; 28

C.
`-(9)/(2)`;
`(1)/(28)`

D. 18; 112

Answer 1

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

Explanation:

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

y = 28 − (9 x) /(2)
