Find the Equation Using Point-Slope Formula (-4,-2) , (4,12)

line

(- 4, - 2), (4, 12)

y = \frac{7}{4} x + 5

Solution steps

Find the line

y = mx + b

passing through

(- 4, - 2)

(4, 12)

Compute the slope

(- 4, - 2), (4, 12) : m = \frac{7}{4}

Compute the

y

intercept:

b = 5

Construct the line equation

y = mx + b

where

m = \frac{7}{4}

and

b = 5

y = \frac{7}{4} x + 5

f (c) = - 13 c

(2, - 9), (- 1, 6)

g (f) = - 47 f

x = 3 + t, y = - t^{2}

y = 6
