The slope-intercept form:
m - slope
b - y-intercept
We have the slope m = 4. Substitute:
Put the coordinates of the point (2, -3) to the equation of a line:
<em>subtract 8 from both sides</em>
<h3>Answer: y = 4x - 11</h3>
A proctactor to measure in maths
Use the <u>factor pairs</u> of 36. You'll find that he has
9 different ways to arrange them:
<em>1 x 36</em> ... 1 tulip each in 36 vases, or 36 tulips in1 vase
<em>2 x18</em> ... 2 tulips each in 18 vases, or 18 tulips each in 2 vases
<em>3 x 12</em> ... 3 tulips each in 12 vases, or 12 tulips each in 3 vases
<em>4 x 9</em> ... 4 tulips each in 9 vases, or 9 tulips each in 4 vases
<em>6 x 6</em> ... 6 tulips each in 6 vases
What does that "(2,20)" represent?
"y=ax^2" is indeed a quadratic function whose graph opens UP and whose vertex is (0,0). The graph has the shape of a parabola.
