what is the equation of a line that passes through the points (0,5) and (4,8)? write the answer in slope-intercept form.
Sergio039 [100]

Answer:

<h2>y = 3/4x + 5</h2>

Step-by-step explanation:

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept → (0, b)

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (4, 8) and (0, 5) → b = 5.

Calculate the slope:

m=\dfrac{5-8}{0-4}=\dfrac{-3}{-4}=\dfrac{3}{4}

Therefore we have the equation of the line:

y=\dfrac{3}{4}x+5

complete each statement with the appropriate measurement or symbol. 48 c = (fill blank) qt , 96 oz (fill blank) 5 lb , 6 yd, 1 f
DochEvi [55]

Answer:

48 cub = 12 Qt

96 Oz > 5 lb

6 yd 1 ft = 9 ft

6 1/2 lb = 104 oz

Step-by-step explanation:

Use the below key formula to convert the units.

1 cub = 4 Quart

16 ounce = 1 lb

96 ounce = 6 lb

1 yd = 3 feet

6 yd 1 ft = 6*3 + 1 = 18 + 1 = 19 feet

Hope this will help you to understand.

Thank you.
