Question

Graph the line that passes through the points (-1,7) and (-3,5) and determine

Answer 1

Answer:

y = x + 8

Step-by-step explanation:

find slope first:

m = 7-5 / -1-(-3)

m = 2 / 2

m = 1

now find the y-intercept using either ordered pair; plug 'y', 'x', and 'm' into

y = mx + b  to solve for 'b'

7 = 1(-1) + b

7 = -1 + b

8 = b

put 'm' and 'b' into slope-intercept equation of a line, y = mx + b to get:

y = x + 8
