The slope of a horizontal line is <u>zero</u>
<span> y-4=-8(x-1) is linear
===================
</span><span>y=x4 is non linear, it is a parabola or a curved line
===================
</span><span>y-x2=4.5 is non linear as it is curved
===================
</span><span>3x + 5y = 15 is linear</span>
Answer:
y = 3x - 5
Step-by-step explanation:
1) First, place the given equation in slope-intercept form, represented by the formula , to find the slope. Whatever or the coefficient of x-term is will be the slope. Isolate y in the equation:
So, the slope of that line is . Lines that are perpendicular have slopes that are opposite reciprocals, thus the slope of the new line will be 3.
2) Now, use the point-slope formula to find the equation of the new line. Substitute real values for the , and in the equation.
Since represents the slope, substitute in its place. Since and represents the x and y values of one point the line passes through, substitute the x and y values of (-1,-8) into the formula as well. Then, isolate the y in the resulting equation to put the equation in slope-intercept form and find an answer:
