Draw 15 circles then draw + 7 circles add them together you get 22
Pro tip: always assign ratios a variable.
So 8x + 7x = 30; 15x=30; x=2
Now plug in x;
8(2)=16 and 7(2)=14
So the pieces are 16 and 14 cm which adds up to 30.
Use the point-slope form: y-k = m(x-h).
Here, y-[-1]) = (17/14)(x+6), or y+2 = (17/14)(x+6). This could, of course, be solved for y if you wish. Mult. both sides by 14, we get 14y+28=17(x+6).
This becomes 17x + 102 - 14y - 28 = 0, or 17x -14y + 74 = 0 (which is standard form). You could also write 17x - 14y = -74.
