Slide SalGridwalkers · the coordinate plane, slope and lines

Starts at the top of the slide and slides down at a steady slope: slope-intercept form.

Slope-Intercept Form

Slope-intercept form. In MathBound, the free Algebra I adventure game, Slide Sal asks these problems, and the only way past is to solve them.

Part of Linear Functions: chapter 5 of the standard course.

10 questions, no sign-up, nothing saved. Climbs from the basics to harder questions.

What you will practice

Identify Slope and Intercept. Identify the slope and y-intercept from an equation in slope-intercept form.
Graph using Slope-Intercept. Graph a line given an equation in slope-intercept form with an integer slope.
Parallel Lines. Determine if two lines are parallel by comparing their slopes in slope-intercept form.
Perpendicular Lines. Determine if two lines are perpendicular by checking if their slopes are negative reciprocals.
Parallel and Perpendicular. Identify whether two lines are parallel, perpendicular, or neither given their slope-intercept equations.

What

is

the

slope

of

y = - 3 x + 1 ?

Show the worked steps

Answer: $- 3$

Graphing

y = 3 x - 1,

you

plot

(0, - 1)

and

use

the

slope

once.

Show the worked steps

Answer: $(1, 2)$

Which

line

is

parallel

to

y = \frac{- 5}{2} x - 3 ?

Show the worked steps

$Parallel$ $lines$ $have$ $equal$ $slopes.$
$The$ $slope$ $is$ $\frac{- 5}{2},$ $so$ $any$ $line$ $with$ $that$ $slope$ $and$ $a$ $different$ $intercept$ $works.$

Answer: $y = \frac{- 5}{2} x + 4$
