Answer:
a.) (-16,0)(0,12)
b.) (-3,0)(0, 3/2)
Step-by-step explanation:
Plug it in for each.
y= 3/4x+12 (Lets plug in our x intercept of (x,0) and our y intercept of (0,y)
x-intercept
0=3/4x+12
-12 -12
-12=3/4x
-12/(3/4)=x
-16=x
SO, your x intercept is -16 which is point (-16, 0)
Now to do your y intercept in lets plug x in as 0 instead this time:
y = 3/4(0)+12
y = 12
Your y intercept is 12
Now for b its the same process of plugging 0 in for the values let
y-int=-2(0)-4y+6=0
-6 -6
-4y/-4=-6/-4 <- divide both sides by 4
y = 3/2 <- Simplified answer
y int = (0, 3/2)
x-int = -2x-4(0)+6 = 0
+6 +6
-2x = 6
x = 6/-2 <-- Divide both sides by -2
x = -3 <-- Simplify
x-int = (-3, 0)
You subtract 2x from both sides so you would get -3y=8-2x. finally you divide by -3 o both sides so your answer is y=8-2x/-3
Answer:
the first graph on the left
Step-by-step explanation:
Substitute the x- coordinate of the point indicated on the graph into the equation and check that this gives the value of the y- coordinate
(1, 6) ⇒ f(1) = 2
= 2 × 3 = 6 ← correct
(1, 9) gives y = 6 ≠ 9 ← not valid
(2, 8) ⇒ f(2) = 2
= 2 × 9 = 18 ≠ 8 ← not valid
(2, 12) gives y = 18 ≠ 12 ← not valid
