Answer:

The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept

Y= 7/4x + 20 would be the answer

Answer:

Democrats are 44

Independent there is 1

Step-by-step explanation:

55 Republicans
44 Democrats
1 Independent

Since you know there are 5 republicans for every 4 democrats you can divide 55/5 and get 11. Then you would multiply 11 by 4 for the number of Democrats. Then you would add 55+44=99. So there would be 1 independent.
