Question

State the slope and y-intercept for x + y = –15

Answer 1

slope = -1
intercept = -15

Answer 2

so Y is 1 right?

Answer 3

State the slope and y-intercept for 3x + 2y = 16
I dont understand this at all. my son is taking this algebra and has 32 test due tomorrow or he fails and dont get to walk with his classor ever gradulate

Answer 4

I ment Y -0 i think lol

Answer 5

well eqUTIons which contain x and y (no x^2 y^2 etc) when graphed produce a straight line. Now the slope of the line is its gradient or steepness and its intercept is where the line cuts the vertical y-axis. ( where x = 0)
So if we write the expression in slope/intercept form its like

y = 3x + 1

when x = 0 then 3x = 0 and y =1 1 is the intercept
and the slope is the number before the x ie in this case 3

Answer 6

ok great, that helps
