Answer:
D
Step-by-step explanation: Plato test
The intersection of 8th street and J street can be determined by setting up an equation for each line segment given the points mentioned above. Note that the equation of a line can be obtained from two points such that:
y - y1 = m(x-x1), where m = (y2-y1)/(x2-x1)
For instance, the equation for 8th street is given by: y - 4 = [(9-4)/(6-1)]*(x-1). On the other hand, the equation for J street is given by: y + 14 = [(4+14)/(-5-4)]*(x-4). Simplifying the 2 equations we get: Eqn. (1) y = x + 3 and Eqn. (2) y = -2x - 6
Solving the 2 equations simultaneously, we obtain x = -3, y = 0. Thus, if the city council extends 8th street in a straight line, it will intersect J street at (-3,0).
(7,2) it’s just basic graphing

Answer:
hi! this may all seem confusing but don't worry it's easy once you get it!
so we have a line this line y=4x-7 is what we will use to plugin our point
and (0,2) is your point!
2=4(0)+b
2=b
and usually you don't have to do that (HINT: if it's 0,a number it's already b like the number that isn't 0 is b aka the y intercept)
y=4x + 2 would be the answer!
REMEMBER: Parallel is always the same so you will use the SAME SLOPE!
Well what is the slope? Slope is always mx! you can find it using the slope formula if it is not given, like this equation it was given
If this said PERPENDICULAR then it would be negative reciprocal of your slope and same equation!
hope this helps :)
new question: write an equation of the line that contains the point (1,5) and have the same y-intercept as the line 2x+3y=6
so we need to move this from standard form to slope intercept
2x + 3y=6
-3y= -2x + 6
y= 2/3x - 2
now we've solved! our y intercept is now -2 and slope is 2/3x
okay and now let's plug it in!
again let's plugin our point
5= 2/3 (1) + b
4 1/3= b
so! y= 2/3x - 4 1/3
