Which statement BEST explains the relationship between lines GF & HJ?
Pavel [41]

Answer:

Option (4)

Step-by-step explanation:

Slope a line passing through two points (x_1,y_1) and (x_2,y_2) is given by,

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

Since, blue line is passing through two points (-4, -2) and (0, 4),

Slope of the blue line = \frac{4+2}{0+4}

                                    = \frac{3}{2}

Similarly, green line is passing through two points (-4, 1) and (0, -2),

Slope of the green line = \frac{1+2}{-4-0}

                                       = -\frac{3}{4}

Since, \frac{3}{2}\neq -\frac{3}{4}

Neither these slopes are opposite reciprocals.

Therefore, both the lines are neither parallel nor perpendicular.

Option (4) will be the correct option.

Could someone help me please need answer ASAP
Ahat [919]

Here we use altitude rule which states that

Ratio of part of hypotenuse and height= ratio of height and remaining part of hypotenuse .

So here parts of hypotenuses are r and s and h is the hypotenuse. SO we will get

\frac{r}{h} = \frac{h}{s}

Correct option is s.

Write y=-5/8x+3 in standard form using integers?
Ivenika [448]

Answer:

standard form of given equation is 5x - 8y = -3

Step-by-step explanation:

y= \frac{5}{8}x + 3

Standard form of linear equation is Ax + By = C

First we remove the denominator 8

We multiply the whole equation by 8

So equation becomes

8y = 5x + 3

Now we move 5x to the left hand side, we subtract 5x on both sides

-5x + 8y = 3

Now we remove the negative side from -5x  by dividing the whole equation by -1

5x - 8y = -3
