Multiply whatever number is on line 7 by 9.
The line in a fraction means "divided by." 7/9 = 7 divided by 9.
Multiply it by -7/9
63
I'm assuming you mean "7 by 9 inches" In that case, simply multiply to get 63 inches.
5/9 * 9/16 * 7/5 = 7/16
If you mean points of (6, 9) and (7, 1) then the slope of the line is -8
To multiply fractions multiply the numerators together and multiply the denominators together: 4/9 × 5/7 = (4×5)/(9×7) = 20/63
solve anything in brackets before anything else. ex: [7+2(9-4)]8 you would do the 7+2 first, (9) then the parenthesis (5) then multiply the 9 and the 5 (45) and then multiply that by 8 (360)
Multiply them together.
If you mean points of (6, 9) and (7, 1) then the slope of the line is -8
If you mean points of (6, 9) and (7, 1) then the slope of the line is -8
8 x 9 - 7 = 65
