Answer:

a. y = x - 2

Step-by-step explanation:

y = a.x + b

from the graph: x = 0, y = -2 --> b = -2

                          x = 2, y = 0  --> 0 = a.2 -2 --> a = 1

Keep getting this wrong
Minchanka [31]

Remember that the y-intercept is where the function has a value of x = 0 and the x-intercept is where the function has a value of y = 0. Thus, to find the x-intercept and y-intercept, we can substitute these values into the equation and solve for the other variable.


<u>x-intercept</u>

Since the x-intecept has a y-value of 0, we can substitute this into the function and solve for x.

0 = -2x - 3

  • Set up

3 = -2x

  • Add 3 to both sides

x = - \dfrac{3}{2}

  • Divide both sides by -2

The x-value of the x-intercept is -\frac{3}{2} and the y-value is 0, meaning that the x-intercept has coordinates \boxed{(-\frac{3}{2}, 0)}.


<u>y-intercept</u>

Since the y-intercept has a x-value of 0, we can substitute this into the equation and solve for y:

y = -2(0) - 3

  • Set up

y = -3

  • Multiply and simplify

The y-value of the y-intercept is -3, meaning that the y-intercept of the function is \boxed{(0, -3)}.

Answer:

c  tomato 2.5

pepper = 3.5

Step-by-step explanation:

Let t= the price of tomato plants

p  =the price of pepper plants

3t+ 4p = 21.50

5t+ 2p = 19.50

Multiply the second equation by -2

-10t -4p =-39

Add this to the first equation to eliminate p

-10t -4p =-39

3t+ 4p = 21.50

---------------------

-7t    = -17.5

Divide by -7

t = 2.5

Now find p

5t+ 2p = 19.50

5( 2.5) + 2p = 19.50

12.5+2p = 19.50

Subtract 12.5 from each side

2p =7

p =3.5

We want the price of 1 tomato and 1 p

3.5+2.5
