To make Grapetastic Ade requires a certain number of teaspoons of grape flavoring per ounce. The relationship between the number of teaspoons of grape flavoring and the number of ounces of Grapetastic Ade is proportional. 20 teaspoons of grape flavoring make 45 ounces of Grapetastic Ade. 50 teaspoons of grape flavoring make 112.5 ounces of Grapetastic Ade. Which equation represents the number of ounces of Grapetastic Ade, y, in terms of teaspoon flavoring, t?

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
