Write an equation in slope-intercept form for the line that passes through the given point and is perpendicular to the following equation.

point: (−4,−3)

equation: 4x+y=7

perpendicular equation:

the equation is

y = x/4 -2

Step-by-step explanation:

Write an equation in slope-intercept form for the line that passes through the given point and is perpendicular to the following equation

Slope-intercept equation is

y= mx + c

Point: (−4,−3)

Equation: 4x+y=7

For two lines to be perpendicular, the product of their slopes, m1 and m2 must be equal to -1

From the given equation, 4x+y=7

y = 7-4x, y= -4x +7.

slope,m1 = -4

Slope of second perpendicular line

=m2

m1 × m2 =-1

4 × m2= -1

m2=-1/-4= 1/4

y = x/4+ c

From the points (−4,−3) given,

y = -3 and x = -4

Substituting in the equation, y = -x/4+ c,

-3= 1/4×-4 + c

-3 = -1+c

c = -3+1 = -2

So the equation is

y = x/4 -2

you never say the total so we cant find the percentage used for petrol

9 x 8 divided by (5-3)=36
