We can find the equation of line when given two points or a point and the gradient/slope.
In the above line we have two points (0,10) and (10,50),
The slope of the line is therefore 4
Parallel lines have equal slopes or gradient, therefore the slope of the other line is still 4. And the line pases through a point (2,25), hence
Equation will be, (y-25)/(x-2) = 4
= y-25 = 4x-8
= y =4x +17
Thus the appropriate equation is y = 4x +17
Answer:
its 4

Answer:
Casey is correct.
Step-by-step explanation:
Robert's 5 1/8 + 2 1/3 = 7 1/2 is wrong because if 5+2 = 7, I would have to change the denominator of both fractions so they are both the same. The denominator would have to be 24. That would make the fractions 3/24 and 8/24. If you added them together, it would not be able to simplify to 1/2.
Casey's -4 1/2 + 6 3/4 = 2 1/4 is correct because —4 - 6 = 2. In order to make the fractions have the same denominator, you would have to multiply -1/2 by 2 on both numerator and denominator wich would equal -2/4. Now add -2/4 and 1/4 and you get 1/4. If my explaining is confusing, I'm sorry!☜(ﾟヮﾟ☜)
Dos rectas cuyas pendientes son m1 y m2, son perpendiculares si y sólo si m1m2 =-1
with a point and the slope you can find the equation
y-y1=m(x-x1)
as the point is given (-1,-4) then substitute it in the equation
y-(-4)= -2[(x-(-1)]⇒y+4= -2x-2⇒y=-2x-2-4⇒y=-2x-6 and this is the equation of the line that must be graphed
second step)
graph the equation y =- 2x-6, with the points of intersection are for x = 0, y = -2(0)-6= -6 , the point is ( 0,-6) and the other point is for y = 0
0= -2x-6, 2x= -6, x = -6/ 2 = -3, the other point is (-3,0) then the graph is the following, you can see in it the points of intersection
