Answer:
I'm going to use the following as an example.

To find the y-intercept, set x equal to 0 then solve for y.

two times zero is zero, so we have the following equation.

Solve for y

Your first point you will graph is (0, 2).
Now solve for the x intercept. To do this, set y = 0.

4(0) = 0, so you can remove it, and solve for x.


Now the next point you have is (4, 0). plot that point. Connect the two points with a line and you are done.
Answer:
x=3/5
Step-by-step explanation:
3x+5=0
3x=-5
x=-5/3
Area of big rectangle =8x7=56cm²
area of small rectangle =5x4=20cm²
hence area of shaded region=56-20=36cm²
Hold on it might take me a few
y = - 3(x + 1 )² + 2
the equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here vertex = (- 1, 2), hence
y = a(x + 1)² + 2
to find a substitute (1, - 10) into the equation
- 10 = 4a + 2 ⇒ 4a = - 12 ⇒ a = - 3
y = - 3(x + 1)² + 2 ← in vertex form
