y=(1/2)x+4

Step-by-step explanation:

you have 2 points but in order to find slope intercept you need slope so,

(y2-y1)/(x2-x1)

(-1+4)/(8-2)=1/2 =slope

slope intercept:

y-y1=m(x-x1)

y-2=(1/2)(x+4)

y-2=(1/2)x+2

y=(1/2)x+4

What is the answer to this question? <br> 1.4a^2+4a-63

LUCKY_DIMON [66]

Answer:

Step-by-step explanation:

Δ = $4^{2} - 4 * 4 * (-63) = 16 + 16 * 63 = 16 * (1 + 63) = 16 * 64$

VΔ = 4 * 8 = 32

a = (- 4 ± 32) * $\frac{1}{8}$

a' = 7/2

a''= 9/2
