Write a linear equation based on given information. Through (5,-5) and (4,0)
Katena32 [7]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut point with the y axis

We have the following points:

(x_ {1}, y_ {1}) :( 5, -5)\\(x_ {2}, y_ {2}) :( 4,0)

We find the slope:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {0 - (- 5)} {4-5} = \frac {5} {- 1} = - 5

Thus, the equation is of the form:

y = -5x + b

We substitute a point and find b:

0 = -5 (4) + b\\0 = -20 + b\\b = 20

Finally, the equation is:

y = -5x + 20

Answer:

y = -5x + 20

. Write the equation of the line with a slope of -3 and a y-intercept of 10
sergiy2304 [10]

The slope-intercept equation for a straight line as - 3 x + 10.

Slope refers to a number that describes both the direction and the steepness of the line.

The slope-intercept equation for a straight line is given by:

y = m x + b;

where m = the slope and b = the y-intercept.

Here, we are given that:

m = slope = -3

y- intercept = b = 10

Put it in the equation  y = m x + b, we get that:

y = (-3) x + 10

y = -3 x + 10.

Therefore, we get the slope-intercept equation for a straight line as - 3 x + 10.
