There is a line that includes the point (7,-8) and has a slope of 1. what is its equation in slope-intercept form?

y=x-15

Step-by-step explanation:

The slope intercept form is y=mx+b, which m is slope and b is y-intercept. So  we know that slope is 1, so we can replace m by 1 (We will ignore the 1 when the X or Y value is 1). and we got a point, we can replace the x by 7 and y by -8. we will get: -8 = 7+b

We can get the b value: b=-15

So we get y = x - 15

what is the answer to this

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)
