What is the equation of line perpendicular to y-3=-4(x+2) and passee through the point (-5,7
netineya [11]

Answer: y=\frac{1}{4}x+\frac{33}{4}


Step-by-step explanation:

1. By definition, two slopes are perpendicular if their slopes are negative reciprocals of each other. So, let's find the slope of the other line.

2. The equation given in the problem is written in Point-slope form:

y-y_1=m(x-x_1)

Where m is the slope.

3. Therefore, the slope of its perpendicular line must be:

m=\frac{1}{4}

4. You have the point (-5,7), so you can substitute it into the point-slope formula to find the equation of the new line:

y-7=\frac{1}{4}(x+5)

5. In slope intercept form is:

y=\frac{1}{4}x+\frac{5}{4}+7\\y=\frac{1}{4}x+\frac{33}{4}

What is the general form of the equation of the line shown?<br><br><br> Y-2=0<br> y+2=0<br> X-2 = 0
Tatiana [17]

Answer:Option A is correct.

y-2=0

Step-by-step explanation:

Option A is correct.

General form of the equation of the line:  y-2 = 0

Step-by-step explanation:

The general form of the equation is given by:

y = mx +b where m is the slope and b is the y-intercept.

y-intercepts of the line is the value of y at the point where the line crosses the y-axis(i.e x= 0)

From the given figure;

we can see that the line crosses the y-axis at y =2  and also here the slope is , m= 0

therefore, by definition of y-intercepts

y-intercept (b) = 2

Therefore, the equation of line as shoen in figure is:

y = (0)x + 2

or

y = 2

y-2 = 0

Therefore, the general form of the equation line as shown in the figure is:

y-2 =0
