Step-by-step explanation:
Answer:
y=5x-4
slope (m)=5
Explanation:
y=mx+b
m is the slope
b is the y-intercept
since the 5 is in the m, the slope would be 5.
Answer:
(6,6)
Step-by-step explanation:
3x+5y=48
-3x+5y=12
Ok so when you're doing elimination you want to combine all of the like terms. In this case, we need to combine 3x and -3x, 5y and 5y, and 48 and 12. 3x and -3x cancel out, so that leaves you with 10y=60. Solving for y gives you y=6. Now you need to solve for x, so using 3x+5y=48, by plugging in y you get 3x+(5*6)=48. Simplifying that gives you 3x+30=48. Subtract 30 and divide by 3, and you get x=6. Thus the Answer is (x,y) or (6,6)
Fritz is correct, in that the ratio is 1:2
Think of the ratio as a division
10:20 = 10/20
When you divide 10 with 20, you will get a decimal (or simplified fraction)
10/20 = 0.5
0.5 = 50 percent, or 1:2
Fritz is correct, in that 1:2 is the ratio
hope this helps
