Write an equation of the line that passes through the given point and has the given slope.

Mathematics

Minchanka [31]2 years ago
4 0

Answer:

y = -x - 4

Step-by-step explanation:

the equation of a linear graph is y = mx + b

you know the m = -1

so now the equation is y = -x + b

from here, what you could do to find b is...

plug (-1, -3) into the equation

1) x = -1, y = -3

2) -3 = -(-1)  + b

3) -3 = 1 + b

4) -4 = b

or you can look at the y-intercept which is where the line intersects with the y-axis

it seems to be (0, -4)

so "b" would be equal to -4

this makes the final equation y = -x + (-4) or y = -x - 4

Find the slope of the line containing the given pair of points. If the slope is​ undefined, state this. (-8,0) and (4,0)
ahrayia [7]

Answer:

The slope is 0

Step-by-step explanation:

Given

(x_1,y_1) = (-8,0)

(x_2,y_2) = (4,0)

Required

The slope (m)

This is calculated as"

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

m=\frac{0-0}{4 -(-8)}

m=0

<em>The slope is 0</em>

If m&lt;mkl=83. m&lt;jkl=127. and m&lt;jkm=(9x-10). find the value of x
kirza4 [7]

MKL = 83, JKL = 127, JKM = 9x - 10        <em>given</em>

JKL + MKL = JKM                                    <em>angle addition postulate</em>

127 +  83  = 9x - 10                                 <em>substitution</em>

       210   = 9x - 10                                  <em>simplify (add like terms)</em>

       220  = 9x                                          <em>addition property of equality</em>

        \frac{220}{9} = x
