# Question 35045

Feb 22, 2018

No, it does not pass through $\left(- 2 , - 8\right)$, it passes through $\left(- 2 , 10\right)$

#### Explanation:

assuming you mean 'Does the slope $- 4 x + 2$ pass through -2,-8?'

This is in the form $y = m x + c$ where $y$ is the $y$ value, $m$ is the gradient and $c$ is the $y$-intercept.

As the coordinates the first coordinate represents the x value, we should substitute $- 2$ into the equation.

$x = - 2$

$y = \left(- 2 \times - 4\right) + 2 = 8 + 2 = 10$

$\left(- 2 , - 8\right)$ is NOT equal to (-2,10#, therefore it does not pass through that coordinate
