Write the equation in slope-intercept form of the line that passes through the
given points.
7. (−1, 3) and (−3, 1) 8. (−4, 8) and (4, 6) 9. (9, 2) and (−3, −2)
10. Zachary purchased a computer for $1,800 on a payment plan. Three months
after he purchased the computer, his balance was $1,350. Five months after
he purchased the computer, his balance was $1,050. What is an equation that
models the balance B after m months?
11. What does the slope signify in this equation and why?
y = 2x + 1
y = x + 4 y = −__

B = −150m + 1800
In the equation B = −150m + 1800, the slope signifies the
monthly payment amount because the balance decreases by
$150 each month.
