What equation is being represented by this line?

Mathematics

faust18 [17]3 years ago

Answer:

The equation that represented by the line is y = -x + 2

Step-by-step explanation:

The slope-intercept form of the linear equation is y = m x + b, where

  • m is the slope of the line
  • b is the y-intercept (value y at x = 0)

The rule of the slope is m = \frac{y2-y1}{x2-x1} , where  

  • (x1, y1) and (x2, y2) are two points on the line

<em>From the given figure  </em>

∵ The line passes through points (2, 0) and (0, 2)

∴ x1 = 2 and y1 = 0  

∴ x2 = 0 and y2 = 2  

→ Substitute them in the rule of the slope to find it

∵ m =  \frac{2-0}{0-2}=\frac{2}{-2}=-1

∴ m = -1  

→ Substitute it in the form of the equation above

∵ y = -1(x) + b

∴ y = -x + b  

∵ b is value y at x = 0  

∵ At x = 0, y = 2

∴ b = 2

→ Substitute it in the equation above

∴ y = -x + 2

∴ The equation that represented by the line is y = -x + 2

A student says that the slope pf the line for the equation y=20-15x is 20 and the y-intercept is 15. Find and correct the error.
Alla [95]
We have this equation for the slope is: y=mx+b which m is the slope and b is the y-intercept, so we have y=20-15x or y=-15x+20, and we already know that the slope is -15 and y-intercept is 20. As a result, the student's error is that he thinks that 20 is the slope because it is the first number. Hope it help!

What is the slope of the line through (-9, 6) and (-3, 9)?<br> Choose 1 answer:
trasher [3.6K]

Given: Points (-9, 6) and (-3, 9)

Find:  The slope of the line that goes through those two points

Solution: In order to find the slope of the line that goes through the points that were provided we have to use the slope formula.  This formula subtracts the y-coordinates from each other and also the x-coordinates from each other to determine the rise/run which would give us the rate of change.

<u>Plug in the values</u>

  • m = \frac{y_2 - y_1}{x_2 - x_1}
  • m = \frac{9 - 6}{-3 - (-9)}

<u>Simplify the expression</u>

  • m = \frac{3}{-3 + 9}
  • m = \frac{3}{6}
  • m = \frac{1}{2}

Therefore, looking at the given options we can see that the best fitting one would be option A, 1/2.

A, B, and C are collinear, and B is between A and C. The ratio of AB to AC is 1:4. If A is at (-7,-8) and B is at (-3,-5) what a
Galina-37 [17]
To get the coordinates of C we shall proceed as follows:

AB:BC=1:4
B-A=[(-3--7),(-5--8)]=(4,3)
4(4,3)=(16,12)
thus the coordinates of C will be:
(16-3,-5+12)
=(13,7)
