Answer:

y = 2x + 2

Step-by-step explanation:

<h3>Reading the graph!</h3>

The line shown in the figure cuts the y-axis 2 units above the origin, I.e.,

the point (0, 2)

The line also meets the x-axis two units before the origin, I.e.,

the point (-1, 0)

<h3>Intercepts:</h3>

When a line meets both the axes (x-axis and y-axis), it forms intercepts.

There are two types of intercepts:

x-intercept (when the line meets the x-axis)
y-intercept (when the line meets the y-axis)

Each of their length is equal to their distance from the Origin(0, 0)

<h3>Equation of a line (intercept form):</h3>

If the x-intercept is denoted by "a" and y-intercept by "b", the equation if such a line is given by:

$\boxed{ \mathsf{ \frac{x}{a} + \frac{y}{b} = 1 }}$

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>Equation of the line in question:</h3>

x-intercept (a) = -1
y-intercept (b) = 2

$\implies \mathsf{ \frac{x}{( - 1)} + \frac{y}{2} = 1 }$

The sign of the denominator is taken by the numerator:

$\implies \mathsf{ - \frac{x}{1} + \frac{y}{2} = 1 }$

Taking LCM:

$\implies \mathsf{ \frac{ - 2x + y}{ 2} = 1 }$

Cross multiplying:

$\implies \mathsf{ - 2x + y = 2 }$

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Isolating y:

$\implies \mathsf{ \underline{ y = 2 + 2x }}$

That's the equation of the given line!

What is the equation of the line with a y-intercept of 4 and a point (8,8)

vladimir2022 [97]

Answer:

y=1/2x+4

Step-by-step explanation:

to find the slope you need to know the change in y over the change in x

(0,4) and (8,8)

8-4/8-0

slope is 1/2

Give the equation of a parallel line to x=3 going thru (2,5)

Vikki [24]

Answer:

y=3x+5

Step-by-step explanation:

The formula is y=mx +b if m is the slope then 3 goes there. If b is the y intercept then 5 goes there since (x,y)

F(x)= −x^2 + x + 14 Find f(2)

sattari [20]

Answer:

f(2) = 12

Step-by-step explanation:

f(x = −x^2 + x + 14

Plug in:

f(x) = −2^2 + 2 + 14

Solve:

f(x) = −2^2 + 2 + 14

f(x) = -4 + 2 + 14

f(x) = -2 + 14

f(x) = 12

Hope this helped.
