  • which quadrant represents the line that passer through the point(-2,3)with a slope of 3/4

    which quadrant represents the line that passer through the point(-2,3)with a slope of 3/4
    A:3x-4y=17
    B:4x+3y=1
    C:2x+3y=5
    D:3x-4y=-18
    Here we go again,seeing another formula for the first time.
    2.This formula is called the slope-intercept form:Y = mx + b; m is the slope of a line,b is the y-value of the
    y intercept.
    3.This formula allow us to quickly figure out things about a line in the coordinate plane without graphing it
    point by point.
    4.To solve this problem,we need to figure out with answer choice represents slope of 3/4 and contains the
    point at (-2,3).
    5.First we need to rewrite every answer choice into the slope-intercept form:
    But let just do choice D first:
    Rewriting it:3X - 4Y = -18
    - 4Y = -18 - 3X
    Y = (-18)/-4 - (3X)/-4
    Y = 3/4 X + 9/2
    6.This rewritten equation now shows you slope as 3/4 because this is representing the m in the equation.
    7.Now for choices A,B,C do the same.Rewriting each equation to prove that their m or slope is not at 3/4.
    8.In other words,the correct answer is D,but do the math to show that the other choices are incorrect
    反正正確答案是D嘍~
    還有那些錯(cuò)誤的答案錯(cuò)在哪里?

    優(yōu)質(zhì)解答
    通過(guò)點(diǎn)(-2,3),且斜率為3/4
    所以選D啊忘了寫上錯(cuò)誤的答案錯(cuò)在那了能告訴我嗎??A,C 斜率不是4 ,B斜率雖然是4,但是不通過(guò)點(diǎn)(-2,3),即(-2,3)帶入方程,兩邊不等.
