What is the slope of the line that is perpendicular to the line that passes through (-2, 7) and (4, 9)? type a numerical answer in the space provided.

Therefore = -3.

Step-by-step explanation:

i) let us say the slope of the line passing through (-2,7) and (4,9) is .

ii) to find the slope of the line passing through two points (, ) and (,) we use the formula m = . Therefore we can say that   = = .

iii) let us say the slope of the perpendicular line to the line  passing through (-2,7) and (4,9) is

iv) from the formula for the slopes of a line and the line perpendicular to it which is given by × = -1, therefore = -1 ÷   = -3. Therefore = -3

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
