Write the standard form of the line that has a slope of - and y-intercept of -2. Include your work in your final answer. Type yo

ehidna [41]

You need to go from slope-intercept ( $y=mx+b$ ) to standard form ( $ax + by = c$ ).

slope-intercept form of your provided values:
$y=-x-2$
now, solve for x and y
$x+y=-2$

Your answer is $x+y=-2$ .

Solve this system of linear equations. Separate

Sladkaya [172]

Step-by-step explanation:

making x subject in eq 1

x= (-1-9y)/-14

substituting the value of x in eq 2

17(-1-9y/-14)=7+9y

(-17-153y)/-14=7+9y

-17-153y=-98-126y

-17+98=153y-126y

81=27y

y=3

substituting this value of y in eq 1

-14x=-1-9(3)

-14x=-28

x=2

(x,y) = (2,3)

Look at the equation 4x - 8.4 = 2x + 5. The terms 4x and 2x are like terms

xz_007 [3.2K]

In form ax + b = c: 2x - 8.4 = 5

Solution to equation: x = 6.7

Step-by-step explanation:

4x - 8.4 = 2x + 5

2x - 8.4 = 5

2x = 13.4

x = 6.7
