Answer:

The equation in slope-intercept form  that describes a line through (4, 2) with slope 12 will be y = 12x -46

Step-by-step explanation:

We need to find the slope-intercept form of a line that passes through (4,2) and have slope of 12.

The general form of slope-intercept form is: y= mx + b

where m is the slope and b is the y-intercept.

We are given slope m = 12

We need to find y-intercept.

Using the formula y = mx + b

and putting values y=2, x = 4 and m = 12, and finding b

y = mx + b

2 = 12(4) + b

2 = 48+b

=> b = 2-48

b = -46

So, value of b is b= -46

The equation in slope-intercept form will be:

m = 12 and b = - 46

y = mx + b

y = 12x -46

The equation in slope-intercept form  that describes a line through (4, 2) with slope 12 will be y = 12x -46

Answer:

The equation in slope-intercept form is Y = 12X – 46.

Step-by-step explanation:

<u>Step 1: </u>

Using the formula .

Y – Y1 = m (X – X1)

<u>Step 2: </u>

Given Data:

(X1, Y1) = (4, 2)

m = 12.

<u>Step 3: </u>

Substitute the X1 as 4, Y1 as 2 and m as 12 in the given equation.

[Y – Y1 = m (X – X1).]  

Y – 2 = 12 (X – 4)

<u>Step 4: </u>

Multiply 12 with (X -4).

Y – 2 = 12X – 48

Keep ‘Y’ in LHS and move -2 to RHS

Y = 12X – 48 + 2

Y = 12X – 46.

Hence Proved.

Use the graph below to answer the question that follows:
Bas_tet [7]
For this case the amplitude is given by:
 A = (l-1l + 3) / 2
 A = 4/2
 A = 2
 The middle line is given by:
 y = 1
 The period of the function is given by:
 T = l x2 - x1 l
 T = l 0 - 2pi l
 T = l - 2pi l
 T = 2pi
 Answer:
 
Amplitude: 2; period: 2π; midline: y = 1

Answer:

It has none. Angle A is obtuse, so it would have to be opposite the longest side. If side a is opposite angle A, then that is not the case.
