Answer:
A
Step-by-step explanation:
To write the equation, find the slope of the line using the two points. Find the difference in y values over the difference in x values.
Write the equation using the slope m=3/2 and the point slope form.
This is the equation of the line. You can convert it to slope intercept form:
Answer:
Two straight lines with slopes m and m' are parallel when m = m'
Two straight lines with slopes m and m' are perpendicular when m × m' = - 1.
Step-by-step explanation:
Let us assume that the two non-vertical lines in the slope-intercept form are
y = mx + c ........... (1) and
y = m'x + c' ............ (2)
If those two lines are parallel then we can say the slope of them will be the same i.e. m = m'
Now, if given two straight lines (1) and (2) are perpendicular to each other and neither of them is parallel to the axes, then we can write m × m' = - 1. (Answer)
F(4) = 2(4)^3 -5
= 2(64) -5
= 128-5
= 123
Hope this helps!
Kelly? Im not sure actually... Im going with Kelly but im probably wrong
