Answer: y=-3/4x
Step-by-step explanation:
The slope intercept form is when you use the equation y=mx+b (m is the slope and b is the y-intercept). First, let's find the y intercept. The y intercept is what y would be if x is 0. here, you can see that this particular line passes through the origin. So, the y-intercept is zero because when x passes through zero, y is also zero. Next, let's find the slope. The formula for slope is change in y/change in x. Let's randomly choose 2 points off this line. To make this a thousand times easier for us, let's choose the points (-4, 3) and (4, -3). Now, to find the change in y, let's find the difference between the 2 y coordinates we have chosen. To do this we just need to do -3-3, which gives us -6. Now let's find the change in x. To do this we will do the same thing we did to find the change in y but this time we'll use the x coordinates. We will do 4-(-4), which simplifies to 8. Now, we're almost done. Just divide the change in y by the change in x. You will get -6/8. This can be simplified to -3/4. So now we know our slope is -3/4 and our y-intercept is 0. Let's insert them into the equation. y=-3/4x+0. We know that we can just get rid of that 0 because 0 literally means nothing. So our final answer is y=-3/4x. Hope this helps!

Answer:
x= -5
Step-by-step explanation:
distribue -4 to get -12x+8+5=73
combine like terms -12x+13=73
subtract 13 from both sides -12x=60
divide both sides by -12 x=-5
As regard their sides, triangles may be
Scalene (all sides are different)Isosceles (two sides are equal)Equilateral (all three sides are equal)
And as regard their angles, triangles may be
Acute (all angles are acute)Right (one angle is right)Obtuse (one angle is obtuse)Equiangular (all angles are equal)
Answer:
She made the mistake in step 2.
Step-by-step explanation:
Natalia's mistake is that she added 2 to the 7 when she should have subtracted it.
x÷5 + 2 = 7
x÷5 + 2 -2 = 7 -2
x÷5 = 5
Then multiply both sided by 5 to get rid of the division on the left
x = 25
This gives us the answer to x.
