Question

what is the slope of the line given by the following equation? y=-x+4

Answer 1

-1

Answer 2

y = mx + b

Where "m" is the slope.

Answer 3

-1 because

y = (-1) x + 4 is in the y = mx+b form. m, slope, = -1

Answer 4

this can be solved in two ways
input two values into x and record the y values that come out to acquire two points.

Then use the equation
slope = (y2 - y1)/(x2 - x1)
Where (x1,y1) is the point furthest to the left on the x axis

The second way this can be solved is using y=mx+b
y = mx + b
m = slope
b = y-intercept
x = input
y = output

find the y-intercept of the equation by setting x = 0
input the y value you obtain into b of the equation as it is your y-intercept

plug an x value into the equation and collect a y value so you acquire a point

insert that point into your y=mx+b equation and solve for m
