What similarity do the two lines (y=2x+7) and (y=-5x+7) have?
Answer and explanation
Correct answer: Both have the same y-intercept
In the form y=mx+c, c is the y-intercept. In both equations, c=7, so both lines meet the y-axis at (0,7). Their slopes are 2 and -5, so the slopes are not the same; only the second line is decreasing. Exam tip: put x=0 to find the y-intercept.
