 Question 391339: graph y = x + 3 and what is the y- intercept?Found 2 solutions by ewatrrr, stanbon:Answer by ewatrrr(10682)   (Show Source): You can put this solution on YOUR website! ``` Hi, Using the standard slope-intercept form for an equation of a line y = mx + b where m is the slope and b the y-intercept. y = x + 3 y-intercept is (0,3) slope of the line m =1/1 Note: slope tells us as y value changes by 1, x value changes by 1 as well ```Answer by stanbon(57258)   (Show Source): You can put this solution on YOUR website!graph y = x + 3 and what is the y- intercept? ---- You need two points. ---- x-intercept = ? Let y = 0 then x+3 = 0 and x = -3 --- So the x-intercept is (-3,0) =================================== y-intercept = ? Let x = 0 then y = 0+3 and y = 3 --- So the y-intercept is (0,3) ===================================== Plot those two points and draw a line thru them to get: ===================================== Cheers, Stan H. ---
