Answer 1

Answer:

Step-by-step explanation:

so many people on brainly ask about these  type of slope - intercept problems,  makes me pretty sure it's the teachers having a tough time teaching this and not people having a tough time learning it

so  slope-intercept formula looks like  y = mx + b

where y is the output ( range)    m is the slope and b is the offset from zero

sooo, knowing the above,  apply the idea of making a line with a bunch of x inputs to get y  outputs.. but think a bazillion inputs.. of x... like x 1.1 and x of 1.2 and x of 1.3  and continue like that till you've graphed an entire line.  :P

now that you have that concept of making a line,  by using the slope-intercept formula ,  let's figure out what that formula is

we are told the slope is 1

and that it goes thur a point  (P1)  (-5,-8)

we should also bring out the point-slope formula here to, and I know, the names make it hard to remember them.  which is which.  Point-slope means you can plug in a single point into it,    while slope-intercept means where it hits the y axis, or intercepts it.  

formula for the point-slope is

y-y1 = m(x-x1)

where x1 and y1 are from the point  P1 in the form of (x1,y1)

plug in our slope and our point to the point-slope formula and work it to the slope-intercept formula like below ( btw, you always do this, use the point-slope to get to the slope-intercept, unless they just give you the slope-intercept)

y-(-8) = (1)(x-(-5))

y+8 = 1(x+5)

y+8 = x+5

y = x+5-8

y = x-3

that's your slope-intercept formula , if it helps you can write in the slope like this

y = (1)x - 3

but as you can see, that does nothing to change it, so

y = x - 3 is good
