Write the standard form of a line that passes through the given points (4,7) and (0,7)
VARVARA [1.3K]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept → (0, b).

We have the points (4, 7) and (0, 7) → b = 7.

Calculate the slope:

m=\dfrac{7-7}{0-4}=\dfrac{0}{-4}=0

Therefore we have y=0x+7=7

The standard form: Ax+By=C

<h3>Answer: y = 7.</h3><h3><em>It's a horizontal line.</em></h3>

Eddi Din [679]

The expression for the greatest common factor of 20 and 30 using the distributive property is 10(2 + 3)

Pounds of ice = 20

Number of cups = 30

The relation for the distributive property :

a × (b + c)

Expand ;

a × (b + c) = (a × b) + (a × c) = ab + ac

Finding the greatest common factor of 20 and 30 ;

  • 20 = 2 × 10

  • 30 = 3 × 10

(2 × 10) + (3 × 10)

According to the distributive property

(2 × 10) + (3 × 10) = 10(2 + 3)

Therefore, the expression for the greatest common factor is 10(2 + 3)
