Question

Given the linear equation x + y = 5, find the slope of its graph.

- 5

- 1

1

5

Answer 1

its -1

Answer 2

solve for y...
y=-x+5
slope is -1

Answer 3

first we write it in a form called slope-intercept form y=mx+b where (0,b) is the y-intercept of the line and m is the slope of the line. Let's do that:
x+y=5
y=-x+5
now that we are in that form, we know that the coefficient of x will be the slope, so the slope is -1
