Answer:
Step-by-step explanation:
if 45x-b is an equation then b value is the y coordinate of y-intercept (where graph touches the y axis)
Answer:
Step-by-step explanation:
<u>Given points</u>
<u>Midpoint is</u>
- ((-9 + 7)/2, (- 9 + 5)/2) =
- (-2/2, -4/2) =
- (-1, -2)
Step-by-step explanation:
the right equation is :
y-y1=m(x-x1)
y+3=3(x+4)
y+3= 3x+12
y=3x+12-3
y=3x+9
<span>y= 2x ^2 - 8x +9
</span>y = a(x - h)2 + k, where (h, k) is the vertex<span> of the parabola
</span>so
y= 2x ^2 - 8x + 9
y= 2x ^2 - 8x + 8 + 1
y = 2(x^2 - 4x - 4) + 1
y = 2(x - 2)^2 + 1 ....<---------<span>vertex form</span>
