what is the slope of 2x+y=8 and x-y=4

Question

algebra 1 slope substitution

Answer 1

We will need to rearrange the equations into the form y = mx + c, where m and c are some real numbers. In such a form, m will be the slope.

2x + y = 8
y = -2x + 8
y = (-2)x + 8

Thus, the slope in this case is -2.

x - y = 4
y = x - 4
y = (1)x - 4

Thus, the slope in this case is 1.

Answer 2

2x+y=8             and                   x-y=4

y = - 2x + 8                   y =1* x - 4

m = - 2                         m = 1

Answer 3

y = mx + b

and m =slope so your slop is what every is infront of the x..- 2 and 1

(-2 because you have to move it over so it is +y=mx+b

 

Hope this helps!

Answer 4

f(x) = -x + 2.
