Find the equation for intercept x 4 and y -7​

Mathematics
1 answer:
nadezda [96]3 years ago

Answer:

y = \frac{-7x}{4} - 14

Step-by-step explanation:

The equation used to find the equation for a line with two intercepts is called point slope form. y - y_{1} = m(x - x_{1}) , where y_{1} and x_{1} are the intercept points and m is the slope.

However, we need the slope to use this formula.

Use m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}

m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}

m = \frac{((0) - (7))}{((4) - (0))}

m = \frac{-7}{4}

y - y_{1} = m(x - x_{1})

y - ( -7 ) = m ( x - ( 4 ) )

y - ( -7 ) = -7/4 ( x - ( 4 ) )

y + 7 = -7/4 ( x + 4 )

y + 7 = \frac{-7(x+4)}{4}

y + 7 = \frac{-7x-28}{4}

y + 7 = \frac{-7x}{4} - 7

y + 7 = \frac{-7x}{4} - 7 - 7

y = \frac{-7x}{4} - 14

a line segment has (x1,y1) as one endpoint and (xm,ym) as its midpoint. Find the other endpoint (x2,y2)of the line segment in te
svlad2 [7]

(x1,y1)

(x2,y2)

(xm,ym)

Midpoint formula is given as below.

((x1 + x2)/2 , (y1 + y2)/2 )

Where

(x1 + x2)/2 = xm ----------- (1)

(y1 + y2)/2 = ym ----------- (2)

Equation (1) implies that;

x1 + x2 = 2xm

x2 = 2xm – x1

Equation (2) implies that;

y1 + y2 = 2ym

y2 = 2ym – y1

Thus the end point is

<span>(x2,y2) = (2xm – x1, 2ym – y1)</span>

A foam toy is 2 inches wide. It doubles in size for every minute it is in water. Write an expression for the width of the toy af
Solnce55 [7]

it would be 2(2^5), which is two times two to the fifth power. you take the original size and double it for every minute, which is like squaring it, but to the power of five, because it doubles once every minute for five minutes. i hope this makes sense!:)

Given the function ƒ(x) = 20x2 − 18x − 25, find ƒ(−1).
dlinn [17]

f(x) = 20x² - 18x - 25

f(-1) = 20(-1)² - 18(-1) - 25

= 20 + 18 - 25

= 13
