Determine the equation of a line perpendicular to -6x + 9y – 12 = 0 with the same y-intercept as the line defined by -8x + 2y – 6 = 0.

The Quicks are driving to their vacation home. After driving for 3.25 hours, they are 250 km from the vacation home. Then, after 4.75 hours of driving, they are 150 km from the vacation home. Approximately, how fast are the Quicks driving? hint: Calculate the “Slope” or “Rate of Change” in km/hour

Solve 4x + 3 = -13

Solve P = 2l + 2w for w

Determine the slope and y-intercept of the line 6x – 2y + 10 = 0.hint: rearrange to y = mx + b format
