Slope = -10, y-intercept = -8

It is a linear function in the standard form.

$y = m x + c$ $y = mx + c$

so the coefficient of x is the slope, that is -10
and constant is the y intercept, that is -8

Another example:
$2 y = 6 x + 4$ $2y = 6x + 4$
This is not in the standard form because coefficient of y is not 1

So dividing the whole equation by 2, we get
$y = 3 x + 2$ $y = 3x + 2$

Now it is in the standard form, so coefficient of x is the slope(that is 3) and constant is the y-intercept(That is 2)

How do you find the slope and intercept of f(x)=−10x−8f(x)= -10x - 8?
