A group of workers are picking grapes at a constant rate. An equation that represents the number of baskets of grapes the workers picked over a period of time, in hours, is y = 4x + 3. (a) What are the slope and the y-intercept for the equation that represents the number of baskets of grapes the workers picked over a period of time?

(b) What is the rate of change and the initial amount? Explain the meaning of the rate of change and the initial amount for the situation.

(c) Use graph paper to draw a graph representing the situation. Label the axes appropriately.

the forst and 3rd

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.

a 90 degree rotation across the the origin followed by a reflection across the x-axis.
