Hello!
To the value of b, or the y-intercept, we need to substitute an ordered pair/point into the given equation.
Since we are given two points, we can use those two points to find two different equations.
Remember that ordered pairs are written as (x, y).
A(-2, 4)
y = -3x + b
4 = -3(-2) + b
4 = 6 + b (subtract 6 from both sides)
-2 = b
A) Therefore, the equation of the first ordered pair is y = -3x - 2.
B(5, 2)
2 = -3(5) + b
2 = -15 + b (add 15 to both sides)
17 = b
B) The equation of the second ordered pair is y= -3x + 17.
<u>Final answers</u>:
- A) y = -3x - 2
- B) y = -3x + 17
Answer:
11/12 feet = 11 inches
Step-by-step explanation:
1/3 of the length is the length of each piece:
(1/3)(2 3/4) = 2/3 + 1/4 = 8/12 + 3/12 = 11/12 . . . feet
There are 12 inches in a foot, so 11/12 feet = 11 inches.
Find the numbers and place them in for the letters
Answer:
The x-intercepts are where the graph crosses the x-axis, and the y-intercepts are where the graph crosses the y-axis. An x-intercept is a point on the graph where y is zero, and a y-intercept is a point on the graph where x is zero.
Step-by-step explanation:
Yes. 3/15 can still be simplified
Divide 3 from numerator and denomoinator.
3/3 = 1
15/3 = 5
1/5 is the simplified form.
hope this helps
