If this helps you have to use the formula (x1,y1) and (x2,y2). So for number 1 it would be 7x - 3x and 2y - 4y
Answer:
150% change
Step-by-step explanation:
Formula for Percent change = C =[ (new - old)/ old ]* 100%
C = [ (25 in. - 10 in.) / 10 in. ] = [15/10 ] * 100% = 150 %
Answer:
Slope is m=0

Step-by-step explanation:
The slope of any line that is perpendicular to the y-axis is zero.
The reason is that any line that is perpendicular to the y-axis is also parallel to the x-axis and the slope of the x-axis is zero.
The equation of any line perpendicular to the y-axis is and passes through (a,b) is y=b.
The given point is (-5,-3) hence the required equation is

2x and 7x is the answer of the questions
