Hello!
Slope intercept form is y = mx + b
m is the slope
b is the y-intercept
To turn the equation into the base form we have to get y by itself
-6y = -2x + 24
Divide both sides by -6
Simplify
To get the y-intercept we put 0 in for the x point and b for the y point
The y-intercept is (0, -4)
The slope is 1/3 which means every time x goes up by 3 the y goes up by 1
Other points are (3, -3) (6, -2) and (9, -1)
With 3 or more points we can plot a graph
Hope this Helps!
Given:
Susie has 34 nickels and dimes. Their total value is $2.35.
To find:
The number of nickels and number of dimes.
Solution:
Let the number of nickels be x and number of dimes be y.
Susie has 34 nickels and dimes.
....(i)
We know that,
1 nickel = $0.05
1 dime = $0.10
Their total value is $2.35.
Multiply both sides by 100.
Divide both sides by 5.
...(ii)
Subtracting (i) from (ii), we get
Putting y=13 in (i), we get
Therefore, number of nickels is 21 and number of dimes is 13.
