334 is the answer to the question
Answer:
c
Step-by-step explanation:
Given data:
The given equation of line is y=x/4+5.
The given y-intercept is (0,c)=(0,-3).
The standard equation of line is,
y=mx+c
Compare the given equation with the above expression.
m=1/4
The expression for the slope which is perpendicular to the given line.

The equation of the line which is perpendicular to the given line is,

Thus, the line which is perpendicular to the given line is y=-4x-3.
Answer:
Step-by-step explanation:
-5y = -x + 15
5y = x - 15
y = 1/5x - 3
perp. -5
y - 5 = -5(x + 2)
y - 5 = -5x - 10
y = -5x - 5
The gradient is also known as the slope and we can find it using the slope/gradient formula: (y2 - y1) / (x2 - x1)
To find the gradient/slope, we need to first choose two points on the line. You can choose any two points you like, as long as they are on the line you are trying to find the slope of.
Point 1 = (2,2)
Point 2 = (5,8)
Now, we can plug in these points to the formula and solve.
(8 - 2) / (5 - 2)
6 / 3
2
The gradient of the blue line is 2.
Hope this helps!! :)
