Write an equation in point-slope form and slope - intercwpt form for passes through (1,9),slope =2

point slope form

y-y1 = m(x-x1)

y-9 = 2(x-1)

change to slope intercept form

y-9 = 2(x-1)

distribute

y-9 = 2x-2

add 9 to each side

y = 2x-2+9

y = 2x+7

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
