F(x)-mx+ b, f(-2)=3 and f(4)=1 , what is the value of m and b
NeX [460]

Answer: m=\dfrac{-1}{3}, b=\dfrac{7}{3}

Step-by-step explanation:

Given

Function is  f(x)=mx+b

f(-2)=3

\therefore 3=m(-2)+b\\\Rightarrow b-2m=3\quad \ldots(i)

f(4)=1\\\therefore 1=4m+b\quad \ldots(ii)

from (i) and (ii) we get

m=\dfrac{-1}{3}, b=\dfrac{7}{3}

Write the equation in slope intercept form of a line that goes through (4,9) and has a slope of 1/2
Vedmedyk [2.9K]

Answer:

y = \frac{1}{2} x + 7

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = \frac{1}{2}, hence

y = \frac{1}{2} x + c ← is the partial equation

to find c substitute (4, 9) into the partial equation

9 = 2 + c ⇒ c = 9 - 2 = 7

y = \frac{1}{2} x + 7 ← equation in slope-intercept form
