The gradient or Slope in a linear equation is simply the value "a" in this equation : y = ax + b

And the y-intercept is simply the value b.

so for example, what is the slope of y = 5x + 3 ? What is the y-intercept ? Well the gradient (or slope) is 5, and the y-intercept is 3.

So, for a.

y = -1/2x + 8

it's pretty simple : gradient = -1/2

y intercept = 8

Now for c.

y=\frac{2x-6}{3}

y=\frac{2}{3}x-\frac{6}{3}

y=\frac{2}{3}x-2

So the gradient is 2/3 and the y intercept is -2 (and not +2, be careful there is a negative sign :) )

e.

-2x + 6y - 3 = 0

6y = 2x + 3

y = (2/6)*x + (3/6)

y = (1/3)*x + (1/2)

so the gradient is 1/3

and the y-intercept is 1/2

Good luck, your the best :)

Step-by-step explanation:

if you are given an equation of a form y=kx+b, k is gradient and b is y-intercept

in c you can write this equation as y=(2x/3)-2,so gradient = 2/3 and y-intercept =-2

in e:6y=2x+3

y=x/3+1/2,gradient = 1/3, y-intercept=1/2

Multiply the following polynomial and write the resulting polynomial in descending order. (3x-8)(2x^2+4x-9)

(3x-8)(2x^2+4x-9)=6x^3+12x^2-27x-16x^2-32x+72=6x^3-4x^2-59x+72

Value of the coefficient of the x^3 term is \boxed{6}

Value of the coefficient of the x^2 term is \boxed{-4}

Value of the coefficient of the x term is \boxed{-59}

The value of the constant is \boxed{72}

Hey can you please help me posted picture of question :)

The answer is the answer is C and F.

This is found by inserting the equation above into the quadratic formula or -b plus or minus the square root of b^2 - 4ac over 2a.

With that, you find that the first number is a -3, which eliminates choices B and D.

Then, solving the 4ac portion, you find that inside the square root the number is 29, which gives you the last two answer choices.

Hope this helps!
