Geoff says that changing the value of m while leaving b unchanged in f(x)=mx+b has no impact on th intercepts of the graphs. marcus disagrees with this statement. who is correct? explain your reasoning.

Marcus is correct, changing the value of m and leaving b unchanged has impact in the x-intercept.

Step-by-step explanation:

The linear equation is

f(x) = m*x + b

now, m is the slope and b is the y-intercept, so if we cahenge m, b remains unchanged, so the y-intercept does not change.

now, the x-intercept is when f(x) = 0 = m*x + b

so the x-intercept is = -b/m

We can see that the x-intercept depends inversilt with m, so chaging m will change the x-intercept.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
