Answer: Sowwy if im wrong
Step-by-step explanation:
You first graph the slope and y- intercept.
We know that the slope is -4 and the y - intercept is -1
We know this by the formula y = mx+b
x y
0 -1
1 -5
To check if this is correct we find the pattern of the inputs and outputs
x = 0 + 1 = you added 1 its increasing
y = -1 -5 = -4 = you added -4 its decreasing
we then do rise/run = -4/1 = -4 ( rise is the y - intercept while as run is the x - intercept
we solve it into the formula
y = mx + b
y = -4x + b
y = -4x - 1
its -1 because the x intercept of 0 is paired with -1 of the y intercept
so the graph was correct
y = -4x -1
We want to describe how to graph a linear equation.
The given equation is:
y = -4x - 1
a) To graph it, we need to find two points that belong to the line, then we graph the points, and then we connect them with a line.
To get the points, we just need to evaluate the function in two different values of x.
for x = 0
y = -4*0 - 1 = -1
So we have the point (0, -1)
for x = 1
y = -4*1 - 1 = -5
So we have the point (1, - 5)
Now we just need to find these two points and connect them with a line, the graph can be seen below.
b) To check if the graph is correct we can see two things:
in y = -4*x - 1
The y-intercept is -1, this means that the graph should intersect the y-axis at y = -1
The slope is -4, this means that for each unit increase on x, we should see that the y-value decreases by 4.
Checking those two things we can see if our graph is correct or not.
