Misty correctly determined the equation of the linear function represented by the table of values below to be mc010-1.jpg in slope-intercept form by using the ordered pairs (1, 7) and (2, 5).
Equation of the line
y = mx + c
m = slope of the line
c = constant
m = (y₂ - y₁)/(x₂ -x₁)
(x₁ , y₁) = (1,7)
(x₂ ,y₂) = (2,5)
=> m = (5-7)/(2-1)
=> m = -2/1
=> m = -2
y = -2x + c
for x = 1 , y = 7
=> 7 = -2 + c
=> c = 9
so line of equation
y = -2x + 9
=> 2x + y = 9
