y=x-1

2x-3y=-1

put x-1 in for y and solve

2x-3(x-1)=-1

2x-3x+3=-1

-x+3=-1

-x=-4

x=4

put 4 in for y and solve

y=4-1

y=3

PLEASE HELP WILL MARK BRAINLIEST Write the equation of the line parallel to the given line and passing through the given point.
Naily [24]

The parallel lines have the same slope.

The slope-intercept form: y = mx + b

m - a slope.

We have 6x + y = 4     |subtract 6x from both sides

y = -6x + 4 → m = -6.

The slope-point form:

y-y_1=m(x-x_1)

We have m = -6 and (-2, 3).

Substitute:

y-3=-6(x-(-2))\\\\y-3=-6(x+2)\\\\y-3=(-6)(x)+(-6)(2)\\\\y-3=-6x-12\qquad|+3\\\\y=-6x-9\qquad|+6x\\\\6x+y=-9

<h3>Answer: 6x + y = -9.</h3>

-7-5x+5x+7 simplified​
AysviL [449]

Answer:

0

Step-by-step explanation:

adding -7 to 7, since they are both constants (no variable) gives you 0. Adding -5x and 5x since they both have an x term gives you 0x also written as 0 (0*any number is 0). this gives you a final answer of 0

. What are the equation and slope of the line that is parallel to the y-axis and goes through the point (1,-2)?​
Brrunno [24]
The answer:

x = 1

Explanation:

If the line is parallel to the y-axis it has no slope, so you would only write down the x-intercept.
