Mr. Rijo bought 49 bags of soil one week and 28 bags of soil the next week. Which expression correctly applies the distributive property to show equivalent expressions for the number of bags of soil he bought?
49 + 28 = 4 (7 + 7)
49 + 28 = (7) (7) + (14) (2)
49 + 28 = (7) (14) + (7) (7)
49 + 28 = 7 (7 + 4)

What are the slope and y-intercept of the graph of y=−13x+1

Answers

Slope is -13 and y-intercept is +1

Answer:

Hi there!

Your answer is:

slope: -13

y-int: 1

Step-by-step explanation:

The slope is the x coefficient, rise/run

In this case, its -13/1. Which means it has a slope of -13.

The y int is the constant term.

In this case, its 1. Which means it crosses the y axis at 1

Write the equation of the line with the slope of 10 that goes through the point 8,-2 in point slope form

Answers

Answer:

y=10x+28

Step-by-step explanation:

y=10x+28

y=(10*-2)+28

y=-20+28

y=8

The linear equation of the line is y + 2 = 10(x - 8)

How to determine the line equation?

The slope is given as:

m = 10

The point is given as:

(x1, y1) = (8, -2)

The equation in point slope form is calculated as;

y -  y1 = m(x - x1)

So, we have:

y + 2 = 10(x - 8)

Hence, the linear equation of the line is y + 2 = 10(x - 8)

Is the x intercept always the same as the slope?

Answers

Answer:

We can use the slope-intercept form (y = mx + b). The x-intercept is found by setting y = 0, because that will give us the x-value at which the line crosses the x-axis.

Step-by-step explanation:

Answer:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

Step-by-step explanation:

Are these lines parallel,
perpendicular, or neither?
Line 1 passes through (0,3) and (3,1)
Line 2 passes through (-1,4) and (-7,-5)

Answers

Answer - Perpendicular

First, find the slope of each line by using the point slope formula [(y2-y1)/(x2-x1)]. You should get that the slope line 1 is -2/3 and the slope of line 2 is 3/2. Using this, we can conclude that both the lines are perpendicular because their slopes are opposite reciprocals (meaning you flip one fraction and change its sign to get the other fraction).

What is the slope and equation of a line parallel to the x-axis passing through (3,7)?

Answers

Answer:

We know that the equation is y=7 because it passes through point (3,7), and 7 is the y-coordinate of that point (remember we don't really care about the 3 because since the line is parallel to the x-axis, it will pass through all values of x, so the 3 is irrevalent).

Step-by-step explanation:

The equation of the line passing through the point (3,7) and parallel to the x-axis is y =7.

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

We know that the equation is y=7 because it passes through the point (3,7), and 7 is the y-coordinate of that point (remember we don't really care about the 3 because since the line is parallel to the x-axis, it will pass through all values of x, so the 3 is prevalent.
