For a math class celebration, two math teachers went to the same store to purchase balloons. One teacher purchased 6 large balloons, R, and 12 medium, M, balloons, and spent $35.40. The other teacher purchased 8 large balloons, R, and 3 medium, M, balloons, and spent $23.80. Part A (2 Points): Write a system of equations to represent the costs of a large balloon, R, and a medium balloon please help a step by step answer with the work shown helps me understand a lot thank u

i believe the answer is the polygon, heptagon.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

step-by-step explanation:

a and d
