HELP HELP— Landon left his house at time zero and drove for 2 minutes to the store, at a speed of 8 blocks per minute. Then he stopped and went into the store for 5 minutes. From
there, he drove in the same direction at a speed of 1 blocks per minute until he got to
the bank, which is 8 blocks away from the store. He stopped at the bank for 7
minutes. Then he drove home at a speed of 12 blocks every minute. Make a graph of
showing the number of blocks away from home that Landon is 3 minutes after he
leaves his house, until he gets back home.

step-by-step explanation:

goog be able to you with that maybe

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

explanation:

remove parenthesis:
