Question

Line s has an equation of y = x - 10. Line t is parallel to line s and passes through

(-1,-3). What is the equation of line t?

Answer 1

Explanation:

y = x - 10. the slope here is 1. A parallel line will have the same slope.

y = mx + b

slope(m) = 1

(-1,-3).....x = -1 and y = -3

now sub and find b, the y intercept

-3 = 1(-1) + b

-3 = -1 + b

-3 + 1 = b

-2 = b

so ur equation is : y = x - 2 <=== equation for line t
