The slope is 9
You use the formula y=mx+b and plug in the y and x from the chart. I’m not 100% sure cuz I did this 3 years ago so sorry if it’s wrong!

Hey, I need some help in math I put the pic down below
EastWind [94]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We find the slope with the given points:

m = \frac {y2-y1} {x2-x1} = \frac {401-450} {14-7} = \frac {-49} {7} = - 7

Thus, the line is given by:

y = -7x + b

We substitute a point to find "b":

450 = -7 (7) + b\\450 = -49 + b\\450 + 49 = b\\b = 499

Finally, the equation is:

y = -7x + 499

Answer:

y = -7x + 499

What is the solution to 4(x-1)-2(3x+5)=-3x-1
Margarita [4]

To solve this problem, we need to get the variable x alone on one side of the equation. To begin, we are going to use the distributive property twice on the left side of the equation to expand the multiplication and get rid of the parentheses.

4(x-1) - 2(3x + 5) = -3x -1

4x - 4 -6x - 10 = -3x - 1

Next, we should combine like terms on the left side of the equation. This means we should add/subtract the variable terms and the constant terms in order to simplify this equation further.

-2x - 14 = -3x - 1

Then, we have to add 3x to both sides of the equation to get the variable terms all on the left side of the equation.

x - 14 = -1

After that, we should add 14 to both sides of the equation to get the variable x alone one the left side of the equation.

x = 13

Therefore, the answer is 13.

Hope this helps!
