Answer:

Does not go

Step-by-step explanation:

$x = \frac{10}{3} \\ y = - 2$

$y = kx \\ - 2 = k( \frac{10}{3} ) \\ \\ k = \frac{ - 2 \times 3}{10} \\ \\ k = \frac{ - 1 \times 3}{5} \\ \\ k = - \frac{3}{5}$

So the equation is

$y = - \frac{ 3}{5} x$

M(-10, 15)

$x = - 10 \\ \\ y = - \frac{3}{5} x \\ \\ y = - \frac{3}{5} ( - 10) \\ \\ y = \frac{3}{5} (10) \\ \\ y = 3 (2) \\ \\ y = 6$

The graph Does not go through point M bcz when the value of x = - 10 then the value of y is 6, not 15

Given the graph of a line y=−x. Write an equation of a line which is perpendicular and goes through the point (8,2).

Eduardwww [97]

When a line is perpendicular to another line, the slope is the negative reciprocal of the other line's slope. So in this case, the slope would be 1, since the negative reciprocal of -1 is 1/1 which is 1.

To find the y-intercept, you have to substitute the point (8,2) into y = mx + b

2 = 1(8) + b

b = -6

The equation is y = x - 6
