Warm-Up: Review What You Know

These problems review what you already know about lines.

Which of these equations describes the same line as $y = 2x - 6$ ?

$2x - y = 6$

$2x + y = 6$

$y = -2x - 6$

$y = 2x + 6$

What is the slope of the line $y = -4x + 9$ ?

Read each form directly. Most of these need no rearranging.

What is the $y$ -intercept of the line $y = 7x - 15$ ? Give the $y$ -value only.

The equation $y + 3 = 5(x - 2)$ is in point-slope form. Which point does the line pass through?

$(2, -3)$

$(2, 3)$

$(-2, 3)$

$(-3, 2)$

What is the slope of the line $3x + 4y = 12$ ?

$-\frac{3}{4}$

$\frac{3}{4}$

$3$

$4$

What is the slope of the line $2x - 5y = 20$ ?

Rewrite $y - 4 = 3(x - 1)$ in slope-intercept form. What is the $y$ -intercept? Give the $y$ -value only.
