9the equation of a line in ' slope- intercept form ' is
y = mx + c ( m is the slope and c the y-intercept )
y = 3x + 1 is in this form
with slope = 3 and y-intercept = 1
the graph crosses the y- axis at ( 0, 1 )
from this point moving 3 units vertically up and 1 unit horizontally right gives the point (1, 4 ) . Repeating this gives the point (2, 7 )
Plot the points (0, 1 ), (1, 4 ) and (2, 7 )
Draw a straight line through them for graph of y = 3x + 1
Answer: red dot by the 40
Step-by-step explanation:
The ratio of Nickel coins: Dimes coins: Quater coins is, 9:2:1.
<h3>
What do we mean by ratios?</h3>
- A ratio in mathematics shows how many times one number is contained in another.
- For instance, if a bowl of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.
- The ratio of oranges to the total amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.
So, the ratio of Gavin’s nickels to dimes to quarters:
- Total coins = 156
- Nickel coins: 156 × 9/12 = 117
- Dimes coins: 156 × 2/12 = 26
Quarter coins = Total coins - Nickel coins - Dimes coins
- Quater coins = 156 - 117 - 26
- Quarter coins = 13
Then, the ratio of Nickel coins: Dimes coins: Quater coins is,
117:26:13 ⇒ 9:2:1
Therefore, the ratio of Nickel coins: Dimes coins: Quater coins is, 9:2:1.
