passes through (2, –3) and is perpendicular to y = 4x + 7 in standard form.
y= 4x +7
compare with y = mx +b
so slope = m = 4.
passes through (2,-3)
find b
plug value of x & y in the general equation
-3 = 2*4 +b
-3 = 8 +b
b= -11
the required line is perpendicular to the line y = 4x +7
so its slope will be -1/4
..
The equation will be y = (-1/4)x -11

Perpendicular lines have slopes that are negative reciprocals.
Now use the slope-intercept form,
Use the point (2,-3) to solve for .
