WebOct 6, 2015 · Find the x- and y- intercepts and write as ordered pairs. y=-3x+7. y=-3 (0)+7. y=0+7. y=7. (0,7) ordered pair for y- intercept. y=-3x+7. 0=-3x+7. 0-7=-3x+7-7. WebWe typically express the intercepts by giving the ordered pair, so we say that the x -intercept above is at the point (−2,0) ( − 2, 0) and the y -intercept above is at the point (0,2) ( 0, 2). Notice that the intercept always occurs where x =0 x = 0, and the x -intercept always occurs where y = 0 y = 0.

WebDec 9, 2024 · The y-intercept has two parts: the x-value and the y-value. Note that the x-value is always zero. So, plug in zero for x and solve for y: y = 12 (0) 2 + 48 (0) + 49 (Replace x with 0.) y = 12 * 0 + 0 + 49 (simplify) y = 0 + 0 + 49 (simplify) y = 49 (simplify) The y -intercept is (0, 49).
