Question

There are 26 students in Mrs. Augello’s math class. The number of boys is three less than the number of girls. Write a system of equations that represents the number of boys and girls.

State the slope and y-intercept of the graph of y = x – 7.

Answer 1

Answer:

1. x= y-3

x+y=26

2.The slope is 1 and the y-intercept is -7.

Step-by-step explanation:

1. If x is boys and y is girls

x= y-3

x+y=26

2. the equation is in the form of y=mx+b

m is slope and b is the y-intercept

in y=1x-7 (which is the same as y=x-7) The slope is 1 and the y-intercept is -7.
