what is the y-intercept for the equation
6x-2y=-4?
选择ABCD
A:-2
B:-2/3
C:2
D:2
SLOPE-INTERCEPT FORM
It looks like this:y =mx + b,c being the coefficient and the slope of the line ,b
being the y-value of a line that intercepts or crosses the y-axis.
But the idea really is to rewrite an equation given to you in this form.
6X - 2Y = -4
Now,start change this form to look like y = mx + b
Step 1:6X - 2y = -4,moving the x now.
Step 2:-2y = -4 - 6x getting the y by itself now.
Step 3:y = (-4 - 6x) divided by -2 solving now.
Step 4:y = 2 + 3x rearrange to look like this:y = mx + b
Step 5:y = 3x + 2
Now,try these additional math practice problems:
A.Yes/No:6(Y+5) = 6Y + 5 ,this is an example of the Distributive Property.
B.Yes/No:given 7(P+Q) = 84 is an equivalent to 7P + Q = 84.
C.Yes/No:5P - 9Q = 9Q - 5P this is an example of equivalent expressions.
D.Solve:7(X-2) = 8(X+3) find the value of X

方程 6x-2y=-4 在y轴上的截距（即交点）是什么?
A：-2 B：-2/3 C：2 D：2/3 (题目是2,错了吧?)
（答案明显,是C：2）
直线方程的斜截式
斜截式的表达式是：y =mx + b,m 是直线的系数或斜率,b 是直线和 y轴的截距或交点.
解题的方法是把给你的方程 6X - 2Y = -4 改写为这样的格式
现在,开始把它变化为 y = mx + b 格式
步骤 1:6X - 2y = -4 X项移项：
步骤 2:-2y = -4 - 6x y的系数化为1（即两边同时除以 -2）
步骤 3:y = (-4 - 6x) ÷（-2） 现在完成除法
步骤 4:y = 2 + 3x 整理变形为 y = mx + b 格式
步骤 5:y = 3x + 2
接下来,尝试下面附加的数学习实际练习：
A.对 / 错：6(Y+5) = 6Y + 5,这是一个分配率的例子
B.对 / 错：7(P+Q) = 84 相当于 7P + Q = 84
C.对 / 错：5P - 9Q = 9Q - 5P 一个等式变换的例子
D.7(X-2) = 8(X+3),求 X的值

第一选y = 3x + 2在y轴上的截距应该是2，可是有两个答案是2，是不是打错了
第二题A NO
B NO
C NO
D -38

唉，这美国人什么思维，这些数学问题都不搭调的
从直线方程截斜式，一下跳到解方程恒等变换，然后又干脆变成解方程了。
第1题应该选择D，它下面解释了一大堆，不过就是把原方程6X - 2Y = -4变成截距式y = 3x + 2，D选项的2就是所求的截距。它那么啰嗦，目的就是讲解方程怎么移项。
然后，第2题就是让你根据它上面讲的一大堆，做下面的题目
这一题这不是选择题，是...

然后，第2题就是让你根据它上面讲的一大堆，做下面的题目
这一题这不是选择题，是判断题+解答题，ABCD是四个小题，ABC是判断题
A.6(Y+5) = 6Y + 5，它说这是乘法分配率的例子，显然是错的
B.它说7(P+Q) = 84和7P + Q = 84是同解方程，显然不对
C.它说5P - 9Q = 9Q - 5P是成立的，显然也不对
D.让你解方程7(X-2) = 8(X+3)，很容易解得：X=-38
