Answer:

  y = 6x +1

Step-by-step explanation:

To write the slope-intercept form equation for a line, you need to know the slope and the y-intercept. These can be found from their respective formulas.

__

<h3>slope</h3>

The slope of a line between points (x1, y1) and (x2, y2) is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

For points (-1, -5) and (0, 1), the slope is ...

  m = (1 -(-5))/(0 -(-1)) = 6/1

  m = 6

<h3>y-intercept</h3>

The y-intercept is the value of y where the line crosses the y-axis. That axis is where x = 0. There is a formula that can be used to find the y-intercept from the slope and a point on the line:

  b = y -mx . . . . . y-intercept of line with slope m through point (x, y)

However, one of the given points is already the y-intercept: (0, 1). It tells you b=1.

<h3>equation</h3>

The slope-intercept equation is ...

  y = mx +b

  y = 6x +1

Find the equation of the line through point (2,2) and parallel to y=x+4. Use a forward slash (i.e.”/“) for fractions (e.g. 1/2 f
aleksandr82 [10.1K]

Answer:

The equation of the line is, y = x

Step-by-step explanation:

The constraints of the required linear equation are;

The point through which the line passes = (2, 2)

The line to which the required line is parallel = y = x + 4

Two lines are parallel if they have the same slope, therefore, we have;

The slope of the line, y = x + 4 is m = 1

Therefore, the slope of the required line = 1

The equation of the required lime in point and slope form becomes;

y - 2 = 1 × (x - 2)

∴ y = x - 2 + 2 = x

The equation of the required line is therefore, y = x

A farmer plowed a rectangular section of land for a new crop. The section measures 24 1/2 yd by 38 1/2 yd. Find the total area i
MAVERICK [17]

Answer: 943\dfrac{1}{4}\text{ sq. yds}

Step-by-step explanation:

Given ,  A farmer plowed a rectangular section of land for a new crop.

Dimensions of the section is given by :-

Length by width = 24\dfrac{1}{2}\text{ yd by }38\dfrac{1}{2}\text{ yd}

Since , the area of a rectangle = length x width

Then, the total area in yards of plowed section of land will be:

24\dfrac{1}{2}\times38\dfrac{1}{2}\text{ sq. yds}\\\\=\dfrac{2(24)+1}{2}\times\dfrac{2(38)+1}{2}\text{ sq. yds}\\\\=\dfrac{49}{2}\times\dfrac{77}{2}\text{ sq. yds}\\\\=\dfrac{3773}{4}\text{ sq. yds}\\\\=943\dfrac{1}{4}\text{ sq. yds}

Hence, the total area in yards of plowed section of land =  943\dfrac{1}{4}\text{ sq. yds}
