Need to Solve 2x + 3y =19

1 answer:

4 0

So this is a coordinate system so put it into y=mx+b format so 3y+2y=19 3y=19-2x Y=(-2x+19)/3 Y=-2/3x+19/3 19/3=6 and 1/3 So y=-2/3x+19/3 Put in values for x and y and get answers exg If you put in 3 For x then Y=-2+19/3 19/3=6 and1/3 -2+6 and 1/3=4 and 1/3 X=3 and y=4 and 1/3 (or 13/3)

Find the equation of the line<br> In the form y=mx+b

Aleonysh [2.5K]

Answer:

y = -1/3x + 5

Step-by-step explanation:

-1/3 is the slope because the line goes down 1 unit and right 3 units.

The y-intercept is 5 because that is where the line crosses the y-axis.

Write the equation of the line that passes through the given point and is parallel to the given line.

<u>(Note: this answer is assuming that the equation has to be put in slope-intercept format.)</u>

Answer:

$y = \frac{1}{2} x - \frac{5}{2}$

Step-by-step explanation:

1) Let's use the point-slope formula to determine what the answer would be. To do that though, we would need two things: the slope and a point that the equation would cross through. We already have the point it would cross through, (-3,-4), based on the given information. So, in the next step, let's find the slope.

2) We know that the slope has to be parallel to the given line, $y = \frac{1}{2}x - 8$ . Remember that slopes that are parallel have the same slope - so, let's simply take the slope from the given equation. Since it's already in slope-intercept form, we know that the slope then must be $\frac{1}{2}$ .

3) Finally, let's put the slope we found and the x and y values from (-3, -4) into the point-slope formula and solve:

$(y- (-4)) = \frac{1}{2} (x - (-3))\\y + 4 = \frac{1}{2} (x + 3))\\y + 4 = \frac{1}{2}x+ \frac{3}{2} \\y = \frac{1}{2}x + \frac{3}{2} - 4\\y = \frac{1}{2}x + \frac{3}{2} - \frac{8}{2} \\y = \frac{1}{2}x - \frac{5}{2}$
