Answer:
y = 3/4x+7
Step-by-step explanation:
The slope is 3/4 and a point is (-8,1)
We can use point slope to make an equation for the line
y-y1 = m(x-x1)
y-1 = 3/4(x--8)
y-1 = 3/4(x+8)
y-1 = 3/4x +6
Add 1 to each side
y-1+1 = 3/4 x+6+1
y = 3/4x+7
This is in slope intercept form (y=mx+b)
The function that has a vertex on the y-axis is f(x) = (x - 2)(x + 2)
<h3>How to determine the function?</h3>
For a function to have its vertex on the y-axis, then the coordinate of the vertex must be:
(h,k) = (0,y)
A quadratic function is represented as:
f(x) = (x - h)^2 + k
So, we have:
f(x) = (x - 0)^2 + k
Evaluate
f(x) = x^2 + k
From the list of options, we have:
f(x) = (x - 2)(x + 2)
Expand
f(x) = x^2 - 4
Hence, the function that has a vertex on the y-axis is f(x) = (x - 2)(x + 2)

2x³+2x¹+2x+5+4/x-1
Answer:
y=− 2x−8 is the equation
Step-by-step explanation:
equation for slope is y=mx+b the y intercept is -8 and the slope is -2
(4x+1)(2x+3)=8x*2+12x+2x+3
= 8x*2+14x+3
