<u>Answer:</u>
The equation is y = 2x - 5
<u>Solution:</u>
Here, x= 3; y= 1
We know the slope of an equation is given by y = mx+c
The value of m which is equal to 3 is given in the question.
Putting the value of m in the slope intercept form we get,
y = 2x+c
To find the The value of c, we substitute the value of x and y from any two given point. Lets take x = 3 and y = 1
Therefore, the slope intercept equation becomes y = 2x - 5
Answer: Option c. D: all real numbers R: (y ≥ 8.75)
Solution:
y=x^2+x+9
Domain: all real numbers = ( - Infinite, Infinite)
y=ax^2+bx+c
a=1 > 0, the parabola opens upward: Range: y ≥k
b=1
c=9
Vertex: V=(h,k)
h=-b/(2a)
h=-1/(2(1))
h=-1/2
h=-0.5
k=y=h^2+h+9
k=(-0.5)^2+(-0.5)+9
k=0.25-0.5+9
k=8.75
Range: y≥k
Range: y≥8.75
