Here's a graph of a linear function. Write the equation that describes that function. 8 Express it in slope intercept form. Ente

Stolb23 [73]

Answer:

f(x) = $\frac{1}{2}x+4$

Step-by-step explanation:

Let the equation of the function is,

f(x) = mx + b

Here, m = slope of the line

b = y-intercept

From the graph attached,

y-intercept 'b' = 4

Slope = $\frac{\text{Rise}}{\text{Run}}$

= $\frac{4}{8}$

= $\frac{1}{2}$

Therefore, equation of the function representing the graph will be,

f(x) = $\frac{1}{2}x+4$

Write the equation using function notation f(x). then find f(0) 2x^2 - 3y = 6

Grace [21]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: f(0) = -2$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: 2 {x}^{2} - 3y = 6$

$\qquad \tt \rightarrow \: 3y + 6 = 2 {x}^{2}$

$\qquad \tt \rightarrow \: 3y = 2 {x}^{2} - 6$

$\qquad \tt \rightarrow \: y = \cfrac{2 {x}^{2} - 6 }{3}$

$\qquad \tt \rightarrow \: y = \cfrac{2 {}^{} }{3} {x}^{2} - 2$

[ here, y can be replaced with f(x) because y is a function of x ]

$\qquad \tt \rightarrow \: f(x) = \cfrac{2 {}^{} }{3} {x}^{2} - 2$

$\large\textsf{Find f(0):}$

$\qquad \tt \rightarrow \: f(0) = \cfrac{2 {}^{} }{3} {(0)}^{2} - 2$

$\qquad \tt \rightarrow \: f(0) = 0 - 2$

$\qquad \tt \rightarrow \: f(0) = - 2$

Slope intercept of (2,-12) and (5,6)

nlexa [21]

Answer:

The slope of the line is m=6.

The y-intercept is (0,−24).

The equation of the line in the slope-intercept form is y=6x−24.

Step-by-step explanation:

The slope of the line passing through the two points P=(x1,y1) and Q=(x2,y2) is given by m=y2−y1x2−x1.

We have that x1=2, y1=−12, x2=5, y2=6.

Plug the given values into the formula for the slope: m=(6)−(−12)(5)−(2)=183=6.

Now, the y-intercept is b=y1−m⋅x1 (or b=y2−m⋅x2, the result is the same).

b=−12−(6)⋅(2)=−24.

Finally, the equation of the line can be written in the form y=mx+b.

y=6x−24.

Answer:

The slope of the line is m=6.

The y-intercept is (0,−24).

The equation of the line in the slope-intercept form is y=6x−24.

Solve. Use the strategy "work backward."

cestrela7 [59]

Let that be x

ATQ

$\\ \rm\Rrightarrow 3x-6/5=9$

Arrange accordingly to work backwards(Every thing is reversed)

$\\ \rm\Rrightarrow 9(5)+6/3=x$

$\\ \rm\Rrightarrow 45+6/3=x$

$\\ \rm\Rrightarrow 51/3=x$

$\\ \rm\Rrightarrow x=17$
