( the 6 triangles are blue, which I’m pretty sure they are.)
Since there are 18 yellows and 6 blues, and the question calls for the ratio of the yellows to the blues, the ratio is 18:6. But you always have to simplify. The GCF is 6, so you would divide both of them by 6. The ratio is then 3:1.
The steepness of a slope is determined by the magnitude of the coefficient. Taking the absolute value of all of our numbers, 12 is the greatest in magnitude.
Therefore, the steepest slope is the slope with 12.
