Slope is the m in y = mx + b. So for this case m=4.
For the y-intercept you just have to let x=0, thus:
y = 4(0) - 2
y = - 2.
Slope is 4 and y-intercept is the coordinate (0,-2).

The slope is 4. The y-intercept(when X=0) is -2 (negative 2).

These guys are correct. The slope is 4 and the y-intercept is -2.

slope is 4...
y-intercept is -2....
your equation is already in the form y = mx + b where m is the slope equal to 4 and b is the y-intercept equal to -2

The numbers given by previous answers are correct. For a method of verifying try making a table. Choose several values for x. Plug them in and solve for y. You know that the slope is the rise over run or rather vertical divided by horizontal "displacements" of values. Do the math. (y2-y1)/(x2-x1) = slope. You have the table, just plug and chug. Suggested values of x are -3, -2, -1, 0, 1, 2, 3, 4, 5
Good luck. You can also use a spreadsheet, but why when it is so easy with pen and paper.

the slope is 4 and the y-intercept is -2, isn't it?

First: the slope is a fraction/whole number beside the "x" variable...in this case the slope is 4
Sec: the y-intercept is a fraction/whole number placed after the "x" variable....in this case, the y-intercept is - 2

Slope = 4
Y-Intercept = (0,-2)

Slope-intercept form:
y=mx+b
m=slope
b=y-intercept
Slope:4
y-intercept:-2

You already have them.
y=4x-2 is in the form
y=mx+b
where the slope is m=4 &
the y-int is b=-2
