answer: -3
remember the equation y = mx + b
m is the slope, and b is the y-intercept
so in the equation y = 4x - 3,
4 replaces the m as the slope and -3 replaces b for the y-intercept
so -3 is your answer
Answer:
parallel
Step-by-step explanation:
x=4 and x=-6 are both vertical lines
Vertical lines are parallel (they both have undefined slopes)
Heyyyyyyyyyy! I think 1 of each because- y’a I just think that.
Answer:
f(x)= -|x + 1| + 1
Step-by-step explanation:
This is an absolute value equation, because it's that v-shape that let's us know it will be one. The standard form is
f(x)= a|x - h| + k, where h is the horizontal shift, k is the vertical shift, and a is the dilation factor.
We know that the graph is moved up one, because its vertex is at y = 1. So k = 1.
f(x)= a|x - h| + 1
We also know that it must be negative, because it's upside-down, so <em>put the negative outside the absolute value, not inside.</em>
f(x)= -|x - h| + 1
Lastly, the horizontal shift is left one, so we know that h = -1.
f(x)= -|x - -1| + 1
x minus a negative one equals x plus one, so
<u>f(x)= -|x + 1| + 1 </u>is our final answer.
Answer:
(a) 
(b) 
Step-by-step explanation:
Given
Variation: Inverse proportional.
This is represented as:
See attachment for table
Solving (a):
First convert variation to equation
From the table:
So, we have:
Substitute 4 for k in
Solving (b): x when y = 25.
Substitute 25 for y in
Cross Multiply
Divide through by 25
Take positive square roots of both sides
