Linear Equation and Slope

Which line has a
positive slope?

• Blue

• Red

• Purple

• Green

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

• y=-1x+3

• y=4x+3

• y=¼x+3

• y=-4x+3

Rewrite the equation in slope intercept form (Solve for y):
 -5x + 6y = 12

• 6y = 5x + 12

• y = (5/6)x + 2

• y = (-5/6)x + 2

• y = (-5/6)x + 12

what is the slope of the line perpendicular to: y = 2/3 x - 1

• -1

• 2/3

• 3/2

• -3/2

Solve for x: 5x + 2 - 10x = 22

• 4

• 4.4

• -4

• -4.4

Write a linear equation in slope-intercept form give the point and slope. (-6, -11); slope = 1/2

Write a line equation in standard form given the point and slope: (3, -8); slope = -3

Write an equation in slope-intercept form given the point and slope: (-4, -7); slope = 1

Starting at sunrise, the temperature rose 2.5⁰ every hour. After 8 hours, the temperature was 67⁰. Write an equation in point-slope form to model the temperature, y, after x hours after sunrise. If sunrise was at 6:00 AM, what is the temperature at noon?
