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
