Answer:
Graphing
Step-by-step explanation:
1) You can graph this equation by using y=mx+b. You can replace that equation with y=3x-1.
M=3
X=x
B=-1
On a graph you would down 1 since it's negative and make a point. Then you would put a 1 under the 3 to make it a fraction. 3/1. Then you would divide 1 by 3 (1 ÷ 3). Then you would go to the right 0.33 because it's positive, and the up 1. Then you would make a second point.
This would only give you one line which wouldn't give you an intersection.
Answer:
36 and 144
Step-by-step explanation:
Sum the parts of the ratio, 2 + 8 = 10 parts
Divide the sum of the 2 numbers by 10 to find the value of one part of the ratio.
180 ÷ 10 = 18 ← value of 1 part of the ratio, thus
2 parts = 2 × 18 = 36
8 parts = 8 × 18 = 144
Thus 2 numbers are 36 and 144
