Write the equation of the line with (1,-7) and -1, in slope intercept form

y = -x - 6

Step-by-step explanation:

We can use the slope intercept form expression [ y = mx + b ], the slope, and the point to find the y-intercept.

-7 = 1(-1) + b

-7 = -1 + b

-6 = b

Input the data we know back into the expression.

y = -x - 6

Best of Luck!

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
