HSPA/ACCUPLACER PROBLEM OF THE DAY
Line k passes through the points (4, 2) and (6, 5), as shown on the grid below.
a. What is the slope of line k? Show or explain how you got your answer.
Sample 1:
5–2 3
=
6–4 2
Sample 2: By looking at the grid, the change is 2 units to the right and three units up.
The slope is positive because it goes up from left to right. Since the change
in y is the numerator (top) and the change in x is the denominator (bottom)
3
the slope is .
2
b. What is the y-intercept of line k? Show or explain how you got your answer.
The y-intercept is –4 because this is the point where the graph crosses the y-axis.
c. Write an equation that represents line k. Show or explain how you got your equation.
y=
3
x–4
2
In the form y = mx + b, m represents the slope and b represents the yintercept. Replace m with the slope which is
intercept which is –4.
