Equation in slope-intercept form is y = 2x - 6
Step-by-step explanation:
- Step 1: Given slope of the line, m = 2. Form an equation y = mx + b
⇒ y = 2x + b ---- (1)
- Step 2: The line passes through the point (4,2). So it will satisfy the equation. Find b by substituting x = 4 and y = 2.
⇒ 2 = 2 × 4 + b = 8 + b
⇒ b = -6
- Step 3: Form the slope-intercept equation.
⇒ y = 2x - 6

Answer:
432 in²
Step-by-step explanation:
To Obtian the square inches of wooden boards required :
Area of box = 2(l * w) + 2(l * h) + 2(h * w)
Length = 12 ; width = 6 ; height = 8
Hence,
Area of box = 2(12 * 6) + 2(12 * 8) + 2(8 * 6)
Area of box = 2(72) + 2(96) + 2(48)
Area of box = 432 in²
We know that:
1 quart = 4 cups
1 cup = 0.0625 gallons
And given is:
2 cups = 9 cups of soup
so,
1 cup = 4.5 cups of soup
going back to the top and using that equation:
1 quart= 4 cups
1/4 quarts = 1 cup
so,
1/4 quarts = <span>0.0625 gallons
</span>to make it 6 quarts:
(1/4)x 24 = 24 x 0.0625
6 quarts = 1.5 gallons
