Answer:
The point-slope form would be y + 6 = -4(x + 1) and the slope-intercept form would be y = -4x - 10
Step-by-step explanation:
In order to find the point-slope form, you simply need to put the point and the slope into the base form.
y - y1 = m(x - x1)
y - -6 = -4(x - -1)
y + 6 = -4(x + 1)
Now to find the slope-intercept, simply solve for y.
y + 6 = -4(x + 1)
y + 6 = -4x - 4
y = -4x - 10
Answer:
b= fifteen over four
Step-by-step explanation:
b= 1/4 + 3 1/2
...6 and 10 are roots, so x – 6 and x – 10 are factors.
y = a(x – 6)(x – 10).....plug in the point (8, 2) and solve for a:
2 = a(8 – 6)(8 – 10)
2 = –4a
a = –1/2
...y = (–1/2)(x – 6)(x – 10)
...y = (–1/2)(x² – 16x + 60)
...y = (–x²/2) + 8x – 30 <<<------Answer, or:
...y = (–1/2)(x – 8)² + 2 <<<------Answer

Answer:
a = 3
Step-by-step explanation:
Evaluating the given function at the point, we have ...
f(-1) = a(-1)^2 +1 = 4
a +1 = 4
a = 3
The value of 'a' is 3.
