What is the slope of the line that passes through the points (4, 7) and (8, 9)

SSSSS [86.1K]

Answer:

y = 0.5x + 5

Step-by-step explanation:

Use the slope formula to find the slope of a line given the coordinates of two points on the line.

The slope formula is:

m = $\frac{y{2}-y{1} }{x{2}- x{1} }$ = $\frac{y}{x}$

The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

Now let's fill in the formula with the points,

m = $\frac{8-4}{9-7}$

Solve,

⇒ Y = 9 – 7 = 2

⇒ X = 8 – 4 = 4

m = $\frac{8-4}{9-7}$ = $\frac{2}{4}$

Simplify,

⇒ $\frac{2}{4}=\frac{1}{2}=0.5$

Therefore, the Equation of the line is y = 0.5x + 5.

At which values of x does the graph of the function F(x) have a vertical asymptote? Check all that apply. f(x)=x+4/x^2+5x-24

mr Goodwill [35]

Answer:

x = -8 & at x = 3

Step-by-step explanation:

This is a rational function.

We can get the values of x at which vertical asymptotes occur by setting the denominator equal to 0 and solving for x.

Let's do this:

$x^2+5x-24=0\\(x+8)(x-3)=0\\x=-8,3$

Hence, vertical asymptotes occur at x = -8 & at x = 3
