Answer:

y = -7/2x + 17/2

Step-by-step explanation:

Slope = (-9 - - 2)/(5 - 3)

= -7/2

y-intercept: -2 - (-7/2)(3)

= -2 + 21/2 (-2*2+21)/2

= 17/2

Solve the equation 12x-14=4x+10

ziro4ka [17]

Answer:

x=3

Step-by-step explanation:

12x-14=4x+10

Subtract 4x from each side

12x-4x-14=4x-4x+10

8x - 14 = 10

Add 14 to each side

8x - 14+14 = 10+14

8x = 24

Divide each side by 8

8x/8 = 24/8

x = 3

tester [92]

Set up a proportion. take 3/6 = 20/x
Cross multiply 3 * x = 6 * 20
Simplify 3x = 120
Divide by 3 x = 40
So the denominator of the bottom fraction is 40

Write the equation in standard form of the line that has x-intercept 6 and y-intercept -2.

zysi [14]

Answer:

x - 3y = 6

Step-by-step explanation:

Equation of the line in intercept form

The intercept form of the equation of a line is:

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

Where:

a = x-intercept

b = y-intercept

The standard form of a line is:

Ax + By = C

The given line has a=6 and b=-2, thus:

$\displaystyle \frac{x}{6}+\frac{y}{-2}=1$

Multiplying by 6:

x - 3y = 6

This is the required standard form of the line.

Thus, the standard form of the line is:

x - 3y = 6
