Answer:
Step-by-step explanation:
So first thing is that slope intercept form is setup like this
y=mx+b
m=slope
b=y intercept
the slope is change in y over change in x
as y goes down 2 x goes up 5
so the slope is -2/5
the y intercept is at (0,-1) so the y intercept is -1
therefore the answer is
have a great day :)
Answer:
Step-by-step explanation:
In order to find the answer, we first need to know the slop form.
y=mx+b
In order to find the slope (m), we need to find at least 2 clear points on the graph. Looking at the graph, we can see that one point is (-5, 1) and (0, -1).
We can use either the formula or rise over run. In this scenario, looking at the graph and using rise over run will be the fastest way. Starting at point (0, -1), you have to rise 2 and run 5.
In addition, the line is going into infinite value in the second and fourth quadrant. This tells us that the slope is negative. .
To find the b value, all we have to do is find the y-value that is on the y-axis. (0, -1), and the answer is -1.
This, gives use the formula
If you want to check your answer, simply plug in a random point on the line into the formula and the equation will be valid.

Answer:
second option
Step-by-step explanation:
Given
+ 6x² + 5 = 0
let u = x², then
u² + 6u + 5 = 0 ← in standard form
(u + 1)(u + 5) = 0 ← in factored form
Equate each factor to zero and solve for u
u + 1 = 0 ⇒ u = - 1
u + 5 = 0 ⇒ u = - 5
Change u back into terms of x, that is
x² = - 1 ( take the square root of both sides )
x = ± = ± i ( noting that
= i ), and
x² = - 5 ( take the square root of both sides )
x = ± = ±
= ±
×
= ± i
Solutions are x = ± i and x = ± i
To solve this, we need to understand Slope Intercept Form (SIF), as well as how to graph a line.
SIF is the standard equation of lines on graphs. It is "y=mx+b" where m is the slope and b is the y-intercept. The y-intercept is the value of y when x is 0.
To find the y-intercept (which we will need to form the equation), we should simply graph the line. This will let us visualize the y-intercept, and overall make it easier to understand.
To graph a line, we should start with the point we have (that being (3, 3)) and follow the slope with rise/run. This means in this case, we will go right 2 for every 1 up, or 2 left for every 1 down.
Below I have attached a graph to help you see how to graph this, which we will get our equation from. The highlighted area is our y-intercept. The red circle shows our original point (3,3), and the blue dots show our slope.
Using the graph, we can see the equation for this line is y=1/2x+1.5.
