Answer:

y = (-3x/5) +1

Step-by-step explanation:

We know that the line passes through the point (-5 , 4)

AND

the slope is given to be -3/5

let's look at the slope a bit more

we know that the formula for slope of a line is Rise / Run

Which means that the rise of this line is -3 after spanning 5 units to the right

Hence, the line goes down 3 units after moving 5 units to the right

We know that to find the equation of a line through the point-slope equation, we need the slope as well as the y-intercept of the line

since we are already given the slope, we need to find the point where the line intersects the y-axis

Now, back to the given point the line passes through

this point has a x - coordinate of -5 and we know that after moving 5 units to the right, the line moves 3 units downwards

So, if the line moves 5 units to the right from the given point, it will reach the y- axis and we know that it's y-coordinate will decrease by 3

Hence, the y-intercept will be 3 units below the given y -coordinate

y - intercept = (4 - 3) = 1 = y-intercept

Now, using the slope-intercept formula to get the equation:

y = (slope)*x + (y-intercept )

y = (-3/5)x + (1)

y = (-3x/5) + 1

Answer:solve for x

-3x+5y=-15

Add -5y to both sides

-3x+5y+-5y=-15+-5y

-3x=-5y-15

Divide both sides by -3

-3x/-3=-5y-15/-3

x= 5/3 y +5

I hope that's help!

What is the equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3

andreyandreev [35.5K]

Answer:

The equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3 is $y+6=\frac{1}{3}(x+2)$

Solution:

Given that line passes through (-2, -6) and has slope of 1/3

We have to find the equation of the line

The point slope form is given as

$y-b=m(x-a)$

where m is the slope of the line and a, b are the x, y coordinates of the given point through which the line passes.

Here in this question, m = 1/3 and a = -2 and b = -6

By substituting in point slope form we get,

$y - (-6) = \frac{1}{3}(x - (-2))\\\\y + 6 = \frac{1}{3}(x + 2)$

Hence the equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3 is $y+6=\frac{1}{3}(x+2)$

Make x the subject of the formula y = mx + b

zubka84 [21]

Step-by-step explanation:

y=mx+c

Take c from both sides:

y-c = mx

Divide both sides by m:

(y-c) / m =x

Now swap sides to make it prettier:

x = (y-c) / m

PLEASE HELP ME SOLVE THIS THANK U!!

Step 1) Draw a dashed line through the points (0,6) and (4,7). These two points are on the line y = (1/4)x+6. To find those points, you plug in x = 0 to get y = 6. Similarly, plug in x = 4 to get y = 7. The dashed line indicates that none of the points on this line are part of the solution set.

Step 2) Draw a dashed line through (0,-1) and (1,1). These two points are on the line y = 2x-1. They are found in a similar fashion as done in step 1.

Step 3) Shade the region that is above both dashed lines. We shade above because of the "greater than" sign. This is shown in the attached image I am providing below. The red shaded region represents all of the possible points that are the solution set. Once again, any point on the dashed line is not in the solution set.
