Answer:
Step-by-step explanation:
I am not sure about point slope, but I can find an equation in slope-intercept form and convert it, so
y=mx+b, m=slope
slope=(y1-y2)/(x1-x2)
we have points
(4,5)
(-3,-1)
(x,y)
x1=4
y1=5
x2=-3
y2=-1
subsitute
(5-(-1))/(4-(-3))=(5+1)/(4+3)=6/7
y=6/7+b
sybsitute and solve for b
(4,5)
x=4
y=5
5=6/7(4)+b
5=24/7+b
5=35/7
subtract 24/7 from both sides
11/7=b
y=6/7x+11/7
convert to the point slope form and find equivilent fraction
since the question asks for 2 answers that are correct and only 2 of the equations have slope of 6/7 I can guess that the answers are B and C
to find slope, we can use the formula
m = (y₂-y₁) / (x₂-x₁)
we are already given two sets of points, so now we can plug it into our equation
x₁ = -4
y₁ = 2
x₂ = 5
y₂ = 8
m = (8-2) / (5-(-4))
m = 6 / 9
m = 2/3
the slope of the line through the points given is 2/3
F(x) = sqrt ( 1/3 x + 2)
To find the domain set the radicand equal to zero and solve.
1/3 x + 2 = 0
Subtract 2 from both sides
1/3 x = - 2
Multiply both sides by 3
x = -6
We know that the radicand must be positive so
x > = -6
The last option
Answer:
The slope is 9/5
Step-by-step explanation:
To find the slope, we use the following slope;
m = (y2-y1)/(x2-x1)
Thus, we have
m = (55-10)/(50-25)P
m = 45/25 = 9/5
