Parallel to y=2x+1 Goes through (5,4)

1 answer:

6 0

      y = mx + b
      y = 2x + 1
y - y₁ = m(x - x₁)
y - 4 = 2(x - 5)
y - 4 = 2(x) - 2(5)
y - 4 = 2x - 10
+ 4     + 4
   y = 2x - 6

If x varies inversley as y and x=4 when y =8, find x when y=1

nikitadnepr [17]

Answer:

x = 32

Step-by-step explanation:

If x and y vary inversely, then xy = k where k is the constant of proportion

4(8) = 32 = k

Now, xy = 32

1(x) = 32

x = 32

Help please. <br> Give the slope of y - 3 = 4(x + 8) and a point on the line

Sauron [17]

-----------------------------------------------------------
Make y the subject :
-----------------------------------------------------------
y - 3 = 4(x + 8)
y - 3 = 4x + 32 // Apply distributive property
y = 4x + 35 // Add 3 to both sides

-----------------------------------------------------------
Identify Slope :
-----------------------------------------------------------
Slope = 4

-----------------------------------------------------------
Find a point on the line :
-----------------------------------------------------------
When x = 0,
y = 4(0) + 35 // Sub x = 0 into the equation
y = 35 // Combine like terms
Point = (0, 35)

-----------------------------------------------------------
Answers :
(a) Slope = 4
(b) One point on the line is (0, 35)
