Answer:
y-intercept is 1
Step-by-step explanation:
We need to find the equation of the line first.
<h3>Gradient</h3>
The gradient is found using the formula:
So the equation is y = 
x + c
<h3>Finding c</h3>
To find c we need to substitute the value of x and y into the equation:
-1 = 
+ c
-1 = -2 + c
1 = c
And c is the y-intercept so it is 1
Step-by-step explanation:
add all the freqency up which is 100
you have to use a customize spinner and put in all the colors that are all on the side...
Spin 150 times ( 250-100= 150) and put tally marks on the sheet of tallys.
Then count all you red and see.
Hope all that makes sense..
Answer:
100 students on each bus
Step-by-step explanation:
100*4 is 400 so there might be just 4
An equation in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
In this case, our y-intercept is 0, so we're left with y = -5x.
-5 is in the place of m, which means -5 is our slope.
The slope of y = -5x is -5.
Just find the vertex and then compare with graph
