How do i graph y=-3/4x-1

Answer:
So start at the y intercept which is -1 in this case becuase the point slope formula goes like
y=mx+b
m= slope
b= y-intercept
Y= Ranodm Y coordinate
X= Random X coordinate
You don’t have to worry so much about the x and Y, the main focus while graphing is the slope (m) and the y-intercept (y)
So -1 is the y-intercept so you go to -1 on the graph on the Y axis, it should be right below 0.
Now to make the points, the slope is -3/4
So a slope is written rise/run
Rise is going up and run is going right
-3 is the rise
4 is the run
Since the slope is negative (due to having a negative on 1 side)
We just do the opposite for the rise
Go down 3 and go to the right 4.
There you have it

Option 2:
Step-by-step explanation:
Given:
From the triangle shown below;
A triangle QRS with angle QRS = 90°, ∠QSR = 30°.
Side QR = 5, SQ = 10 and RS = 5√3
Now, we know from trigonometric ratio that,
Here, opposite side of angle QSR is QR and Hypotenuse is the side opposite angle QRS which is SQ. Therefore,
Therefore, the value of sine of 30° is one-half. So, second option is correct.
