Please help I don't know how to solve also can you explain

Perpendicular: 4, Parallel: -1/4

Step-by-step explanation:

The slope of a line perpendicular to the given line is the opposite inverse of the slope to the line.

First write the equation of the line in slope-intercept form

-x-4y=7

-4y=x+7

y=-(1/4)x-7/4;

The slope to the line is -1/4; Now find the slope of the perpendicular line;

-(-1/4)^-1 = 4

4

The slope of a line parallel to a line is the same as the given slope;

when we calculated the given slope, it was -1/4

The slope of the line parallel to this line is also -1/4

-1/4

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
