Answer:

y = (1/2)x + 1

Step-by-step explanation:

linear line equation is y = mx + b

Where m is the slope and b is the y-intercept when x is 0.

For m, m is change in y(delta y) over change in x(delta x).

We are given two points: (0,1) and (4,3).

m = (y2 - y1)/(x2 - x1) = (3-1)/(4-0) = 2/4 = 1/2

y = (1/2)x + b

Now plug in (0,1) into above equation to find b value.

1 = (1/2)0 + b => b = 1

Final equation is y = (1/2)x + 1

Use implicit differentiation to find an equation of the tangent line to the curve at the given point. 7x2 + xy + 7y2 = 15, (1, 1

riadik2000 [5.3K]

Assume $y=y(x)$ .

$7x^2+xy+7y^2=15$
$\dfrac{\mathrm d}{\mathrm dx}[7x^2+xy+7y^2]=\dfrac{\mathrm d}{\mathrm dx}[15]$
$14x+y+x\dfrac{\mathrm dy}{\mathrm dx}+14y\dfrac{\mathrm dy}{\mathrm dx}=0$
$\dfrac{\mathrm dy}{\mathrm dx}(x+14y)=-(14x+y)$
$\dfrac{\mathrm dy}{\mathrm dx}=-\dfrac{14x+y}{x+14y}$

The slope of the tangent line to the curve at $(a,b)$ is then $-\dfrac{14a+b}{a+14b}$ , so the tangent to $(1,1)$ has slope

$\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{x=1,y=1}=-\dfrac{15}{15}=-1$

The point-slope form of the tangent line is then

$y-1=-(x-1)\iff y=-x+2$

2x-1/2=3-x<br> solve for x.

DanielleElmas [232]

Given,

2x - 1/2 = 3 - x

2x + x = 3 + 1/2

3x = 7/2

3x = 3.5

x = 3.5/3

x = 1.167
