Answer:
I believe it to be C
Step-by-step explanation:
4y-y is NOT equivalent to 4.
4 is multiplied by 'y', and then 'y' is subtracted from that equation. Even if y=1, your equation would look like 4x1-1=3.
Hope that made sense:)
Step-by-step explanation:
The equations with solution x = 1 and y = (-1) will intersect each other at (1,-1) .
<u>Equation</u><u> </u><u>1</u><u> </u><u>:</u><u>-</u>
→ y - (-1) = 1 ( x -1)
→ y +1 = x -1
→ x - y -2 = 0
<u>Equation</u><u> </u><u>2</u><u> </u><u>:</u>
→ y - (-1) = -1( x -1)
→ y +1 = -x +1
→ x + y = 0
Required answer
We know m = 5, x = 3, and y = -2, and that the point slope form is y = mx + b, so plugging these in we can solve for b;
-2 = 5 * 3 + b
-2 = 15 + b
b = -17
So the equation for the line would be;
y = 5x - 17
b is the y intercept, so that is answered (0,-17), to solve for the x intercept you have to plug 0 in for y in the equation, so;
0 = 5x - 17
17 = 5x
x = 17/5
So the x intercept would be (17/5,0)
