What is the equation in the slope intercept form of the line that passes through the point (2,-2) and is perpendicular to the li
Igoryamba

Answer:

D

Step-by-step explanation:

The slope is 2/5 and the slope of the new line will be -5/2 because the negative reciprocal creates a perpendicular line. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.

(y--2)=-5/2(x-2)

y+2=-5/2x+10/2

y=-5/2x+5-2

y= -5/2x+3

The figure below shows a line graph and two shaded triangles that are similar:
VLD [36.1K]
Every time the y-value decreases by 1, the x-value increases by 2, so the slope is -1/2 throughout the line.

What is the product??
tangare [24]

Answer:

The answer to your question is the third choice

Step-by-step explanation:

To solve this problem, just multiply 6 by each of the numbers of the matrix and simplify.

            6   |  4  -2  1 |   =   | (6 x 4)   (6 x -2)   (6 x 1) |  

                 |  7   3   0|        | (6 x 7)   (6 x 3)    (6 x 0) |

                                    =   | 24   -12   6 |

                                         | 42    18    0 |

The first choice is wrong because only multiply by six the first row.

The second and fourth rows are incomplete.
