Slope Intercept Form

Question 1

Write the equation of the line that has a slope of -1/3 and y-intercept of 8.

y = 3x + 8

y = -1/3x + 8

y = 8x - 1/3

Question 2

A company charges $50 per cake and a shipping fee of $7.50, no matter how many cakes you order. Write an equation that represents how much the cakes would cost, y, as a function of the number of cakes, x, you order.

y = 57.5x

y = 7.5x + 50

y = 50x + 7.5

Parallel / Perpendicular Equations

Question 1

Write the equation in slope intercept form of a line that passes through the point (6,10) and is perpendicular to the line represented by y=-3/2 x+19.

y = 2/3x + 6

y = 3/2x + 1

06

Question 2

Write the equation in slope intercept form of a line that passes through the point (1,15) and is parallel to the line represented by y= 8x+2.

y = 8x + 7

y = 8x + 5

06

Question 3

Write the equation in standard form of a line that passes through the point (2,14) and is parallel to the line represented by y= 3x+1.

y = 3x - 8

-3x + y = 8

3x - y = - 8

3x + y = 8
