Answer:
y = 4/3x - 4
Step-by-step explanation:
to find the equation of a line with 2 points, we use the slope formula which is:
we will use (6,4) as and we will use (-3,-8) as
. we plug this into the slope formula:
-8 - 4 = -12
-3 - 6 = -9
the slope is
but we can simplify this further by dividing the fraction by -3
-12 / -3 = 4
-9 / -3 = 3
the simplified version of the slope is
we can write this in slope-intercept form which is y =mx + b, with b being the y intercept and m being the slope
y = 4/3x + b <--- we need to solve for <em>b</em> in order to find the y intercept, so substitute x & y for a point on the line, we can use any point we are given, but for this example i will use (6,4)
4 = 4/3(6) + b < multiply 4/3 x 6
4 = 8 + b < subtract 8 from both sides
-4 = b
our y intercept would be (0,-4)
the equation looks like the following:
y = 4/3x - 4, which is our answer
Answer:
1. Distributive property.
2. Combining like terms.
3. Addition property of equality.
4. Division property of equality.
Step-by-step explanation:
- The Distributive property states that:
- The Addition property of equality states that:
- The Subtraction property of equality states that:
- The Multiplication property of equality states that:
- The Division property of equality states that:
Given the following equation:
We can identify that the methods Maria used to solve it and the order, are:
1. Distributive property:
2. Combining (or adding) like terms:
3. Addition property of equality, because she added 36 to both sides of the equation:
4. Division property of equality, because she divided both sides of the equation by 12:
