Mathematics Achievement
Linear equations and graphs on the ISEE Upper Mathematics Achievement section covers slope, intercepts, and matching a line to points or to the coordinate axes.
A student must rearrange an equation into a useful form, find slope from two points or from an equation, identify which line contains given points, and use intercepts to find a quantity such as the area of the triangle formed with the axes.
Questions are multiple choice and often leave the equation in a messy form so that mixing up slope and intercepts or skipping the algebra leads to a nearby wrong option; choices are usually a number or the equation of a line.
Pick an answer to see whether it is right — nothing is saved, and nothing needs an account.
Question 1Mid
The line crosses the -axis and the -axis, forming a right triangle with the coordinate axes. What is the area of that triangle?
Answer: C — 27
The -intercept is 6 because . The -intercept is 9 because . The triangle’s legs along the axes have lengths 6 and 9, so the area is .
Question 2Easier
Which line contains the two points and ?
Answer: A —
The slope is . Substituting gives the intercept 3, so the line is .
Question 3Mid
What is the slope of the line ?
Answer: C — 6
Subtract 4: . Multiply by 2: . The slope is 6.
