To find the slope intercept form, you plug in the slope and the points given and find whats missing
y=mx+b
slope is -2
given points are (4,-3)
-3=-2(4)+b (multiply -2 and 4)
-3=-8+b (add 8 to both sides)
5=b
so the equation for the slope intercept form would be
y=-2x+5
Answer:
-38
Step-by-step explanation:
10 + 28 = 38 so to check it 10- (-38)=28
Take the co-ordinates of your triangle and add three to the Y co-ordinates and keep the X co-ordinates the same. Then, graph. The shape should have slid upwards three points.
Answer:
x = (-15)
y = 6
z = 3
Step-by-step explanation:
x + y + z = -6______(1)
2x - y - 5z = -21____(2)
-x - y -6z = -9______(3)
(1) + (2)
z = 3, (1) + (2)
x = (-15), (1)
Answer: x = 6
Step-by-step explanation: To solve for <em>x</em>, we must first isolate the term containing <em>x</em> which in this problem is -3x.
Since 28 is being added to -3x, we subtract 28 from both sides of the equation to isolate the -3x. On the left, the +28 and -28 cancel out and on the right 10 - 28 is -18 so we have -3x = -18.
Now we can finish things off by just dividing both sides of the equation by -3. On the left the -3's cancel and we have <em>x</em>. On the right, -18 divided by -3 is 6 so we have x = 6 which is the solution to our equation.
