Answer: The second choice is correct: slope is 3/4, y-intercept is 1
Step-by-step explanation: The y-intercept is where the line crosses the y-axis.
Look for places where the line intersects the grid at "cross-points" like (-4,-2) (0,1) and (4,4)
The slope is rise/run.
The difference in y-values is the rise. 4-1=3 1-(-2) is 3.
The rise is 3.
The difference in x-values is the run. 4-0=4 0-(-4) = 4
The run is 4
Rise/run = 3/4 That is the slope.
Answer:
96cm^2
Step-by-step explanation:
subtract equations to form the equation of:
2x + 2y = 8
rearrange first equation to make x the subject:
x = 4 - 2y
subsitute into 2x + 2y = 8
2 (4 - 2y) + 2y = 8
8 - 4y + 2y = 8
collect like terns
-2y + 8 = 8
8s cancel out
-2y = 0
divide by -2
<u>y</u><u> </u><u>=</u><u> </u><u>0</u>
substitute y value into x + 2y = 4
x + 2 (0) = 4
solve for x
x + 0 = 4
<u>x</u><u> </u><u>=</u><u> </u><u>4</u>
therefore, the solutions are:
<h3>
<u>x</u><u> </u><u>=</u><u> </u><u>-</u><u>4</u></h3><h3>
<u>y</u><u> </u><u>=</u><u> </u><u>0</u></h3>

Answer:
Step-by-step explanation:
A more complicated expression such as 64x3+27y3 64 x 3 + 27 y 3 is also a sum of cubes since 64x3=(4x)3 64 x 3 = ( 4 x ) 3 and 27y3=(3y)3 27 y 3 = ( 3 y ) 3 . Please note, that expressions such as 2x3 2 x 3 are not perfect cubes.
