Solution:

Given equation of line
y=-4x+2 .

The given equation is in the form of y=mx+b, y is isolated. So the coefficient of x is the slope of the line.

The slope of the line y=-4x+2 is -4

To find the y-intercept of the equation, substitute
x=0 in the equation,

$\Rightarrow y=-4(0)+2\\\Rightarrow y=2$

So, y-intercept of the equation is
(0,2) .

Hence, the slope is -4 and y intercept is 2. (first option)

Answer: First option. The slope is -4 and the y-intercept is 2.

Solution:

y=-4x+2

When the equation is in the form:

y=mx+b (y isolated)

The coefficient of the variable "x" is the slope "m" of the right line. In this case the coefficient of "x" is -4, then the slope "m" is -4.

The indeoendent term is the y-intercept "b". In this case the independent term is +2, then the y-intercept "b" is 2.
