Write an equation if the line that passes through (0,-3) and (3,3) .
liq [111]

Answer:

y = 2x - 3

Step-by-step explanation:

y = mx + b

m = (y2-y1)/(x2-x1)

m = (3-(-3))/(3-0)

m = 6/3

m = 2

y = mx + b

y = 2x + b

3 = 2(3) + b

3 = 6 + b

b = -3

therefore

y = 2x - 3

Solve for y. 3=7(1-1)<br><br>(it isn't 2)​
laiz [17]

Answer:

First off, I can't solve for y, there is no y variable.

Second, 3 = 7 ( 1 - 1 ) is not true because 3 ≠ 0 ( 3 doesn't equal 0 ) :

3 = 7 ( 1 - 1 )

3 = 7 ( 0 )  ( Simplify Parenthesis )

3 = 0 ( Multiply 7 and 0 )

3 ≠ 0
