IM2 Quiz #1 Review

What is correct form of the equation of a line in SLOPE-INTERCEPT form?

• 
  

  $y-y_1=m\left(x-x_1\right)$

• $y=mx+b$

• $x=my+b$

• $ax+by=c$

Identify the y-intercept in the following equation of a line:

 $y=\frac{2}{3}x-7$  

• 2/3

• 2

• 7

• -7

Identify the slope in the following equation. (HINT: you'll want to put it in slope-intercept form first)

 $2x+3y=6$  

• 2/3

• 2

• -2/3

• -3

Rewrite the equation given in standard form into SLOPE-INTERCEPT form.

 $4x-5y=-30$  

Evaluate

 $2x^2+6x-3y\ when\ x=-3\ and\ y=2$  

Solve for x.

 $7\left(2-6x\right)=266$  

•  $x=-6$  

•  $x=6$  

•  $x=42$  

•  $x=-42$  

Write the equation of the line in slope-intercept form.

• $y=\frac{5}{2}x+2$

• $y=\frac{5}{2}x-2$

• $y=\frac{2}{5}x-2$

• $y=-\frac{2}{5}x-2$

Write the slope-intercept form of the equation of the line that passes through the point with the given slope.

Through: (4,4), slope= -5

• $y=-5x+4$

• $y=-5x-4$

• $y=-5x+24$

• $y=4x+4$

Write the slope-intercept form of the equation of the line described.
Through: (4, -3) and parallel to

 $y=-4x+4$  

•  $y=\frac{1}{4}x+13$  

•  $y=4x+13$  

•  $y=-\frac{1}{4}x+13$  

•  $y=-4x+13$  

How did you feel about this quiz?

• Not bad! I did pretty well!

• It was okay.

• I could have studied more.

• I didn't know a thing.
