11/15 and 11/16 - Quizizz - Graphing With Slope-Intercept Form

Which of the following are good strategies to use on multiple choice problems?

• See if the slope is positive or negative and eliminate any answers that don't fit.

• See what the y-intercept is and eliminate any answers that don't fit.

• Take your time and think things through carefully.

• All of the above.

What should be your FIRST step when graphing the equation written in slope-intercept form below?

y = 3/4x + 2

• Graph the slope.

• Put a point on the y-axis at 2.

What should be your 2nd step when graphing the equation below?

y = 3/4x + 2

• Graph the slope.

  (Go up 3 then to the right 4 from the point you just put at 2 on the y-axis.)

• Put a point at the x-intercept.

What is the slope of this line?

(Just use Rise over Run.)

• -4/5

• 4/5

• -5/4

• 5/4

What is the Y-INTERCEPT of this line?

(Where does the graph cross the y-axis?)

• 2

• -2

• 3

• -3

Which graph best represents the equation y = -3x + 4?

(Think of -3 as -3/1 so you will have Rise over Run --- so you go down 3 over 1 from your y-intercept.)
