Question

find a linear function h, given h(7)=-28 and h(-4)=27.then find h(2)

h(x)=

(type an expression using x as the variable. Simplify your answer)

h(2)=

(simplify your answer)

Answer 1

the line eats (7,-28) and (-4,27)

the slope m= 55/-11 = -5

B = y - mx = 27 - (-5)(-4)

= 27 - 20

= 7

y = -5x + 7 = h(x)

h(2) = -3
