The line goes 3 right for every 1 down, so the gradient is -1/3
The y-intercept is +4, so the equation is actually y=-1/3x+4, so Chris is wrong.
Vertex form is y=a(x-h)^2+k
you need to find a perfect square
y=x^2+24x+<u> </u>+29 -<u>
</u>y=x^2+24x+144+29-144
y=(x+12)^2 +29-144
y=(x+12)^2-115

Answers:
- slope = 1
- equation is y = x-4
============================================
Explanation:
Two points on this diagonal line are (0,-4) and (1,-3)
Let's apply the slope formula to get the following
m = (y2-y1)/(x2-x1)
m = (-3-(-4))/(1-0)
m = (-3+4)/(1-0)
m = 1/1
m = 1
The slope is 1. We can think of it as 1/1 to indicate "go up 1, and over to the right 1". In other words, slope = rise/run = 1/1.
----------
Note how the graph crosses the y axis at -4, so this is the y intercept.
Since the y intercept is -4, this means b = -4
So with m = 1 and b = -4, we go from y = mx+b to y = 1x+(-4) which simplifies to y = x-4
Answer:
2
Step-by-step explanation:
Since you're only looking at salt and you want 4 times as much all you need to do is multiply 1/2 with 4 and the result is 2.
