Question

Write the slope intercept form of the equation of each line

Answer 1

Answer:

Equation is y = 5x - 6

Step-by-step explanation:

$y = mx + c$

m is slope, and c is y-intercept:

$slope = \frac{y _{2} - y _{1} }{x _{2} - x _{1} }$

(x1, y1) = (1, -1)

(x2, y2) = (0, -4)

$m = \frac{ - 4 - 1}{0 - 1} \\ \\ m = 5$

for y-intercept, consider (1, -1):

$y = mx + c \\ - 1 = (5 \times 1) + c \\ - 1 = 5 + c \\ c = - 6$

substitute in general equation:

$y = 5x - 6$

Answer 2

Y = 2x - 4 is the answer
