Answer:
Step-by-step explanation:
Solving an inequality is very similar to solving an equation, one uses inverse operations. The only major difference between the two is that when one multiplies or divides an inequality by a negative number, one must remember to flip the inequality sign to ensure that the inequality remains true. In this situation, such a rule does not come into play.
Inverse operations,
Answer:
y = - x + 4
Step-by-step explanation:
the student used the y- coordinates of the points in the wrong order.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
m =
with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (5, 1) ← 2 points on the line
m = =
= -
the line crosses the y- axis at (0, 4 ) ⇒ c = 4
y = - x + 4 ← equation of line
