Answer:
y = -3/2x - 5
Step-by-step explanation:
y = mx + b
The line intercepts the Y-axis at -5, so b = -5
From one point to another is 6/-4, which simplifies to -3/2. So m = -3/2.
So to find the equation of the line we just need to plug in the m and b.
Which gives us y = -3/2x - 5 as the slope-intercept equation of the line.
Answer:
.0625 or A
Step-by-step explanation:
You have to work out the mean. (The simple average of those numbers) Then for each number subtract the Mean and square the result. Then work out the average of those squared differences.
Answer:
x=51
Step-by-step explanation:
Answer:
The equation that can be used to solve for a is 1 = a(0=1)²-3.
Explanation:
In this case, I would model the parabola in vertex form. Vertex form is y = a(x-h)²+k, where (h,k) is the vertex of the parabola. Using the information from the question, we can plug in values to get 1 = a(0+1)²-3. (This could be simplified as 1 = a(1)²-3 ⇒ 1 = a-3 ⇒ a = 4, but we are only interested in finding the equation that can solve for a.)
