Answer:
y = 4x+23
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = 4x+b
Substitute the point into the equation
7 = 4(-4)+b
7 = -16+b
Add 16 to each side
7+16 = b
23 = b
y = 4x+23
Answer:
The slope is -2
Explanation:
I choose two points on the graph (0,-2) and (-1,0) and put it into the slope form using two coordinate pairs which is y-y/x-x and got -2/1 which simplifies down to -2
Answer:
The other sides equal 9cm also because a square has four equal sides.
L=9cm * W=9cm =A
A=81 cm
Answer:
x=2x, y=5y
Step-by-step explanation:
180-108=72+120=192,360-192=168
X-y=5
x times y= 84
-7 and -12
