Identify the slope and y-intercept of the function y=5x-10

Mathematics

V125BC [204]2 years ago
3 0

Answer:

slope = 5 , y- intercept = - 10

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x - 10 ← is in slope- intercept form

with slope m = 5 and y- intercept c = - 10

xxTIMURxx [149]

Slope intercept form: y = mx + b

When a line is perpendicular to another line, its slope is the negative reciprocal to that slope.

From this information, we already know that the slope of our new line is -1/2, because -1/2 is the negative reciprocal to 2 (which is the slope of the original line).

y = -1/2x + b

Because the point (-5,3) is given, we can simply plug the x and y coordinates into our incomplete equation.

3 = -1/2(-5) + b

3=2.5 + b

b = 0.5

ANSWER: y = -1/2x + 0.5

THE GRAPH IS LINKED; RED LINE IS y=2x-3 AND BLUE LINE IS y=-1/2x + 0.5

Answer:

(-6, -3)

Step-by-step explanation:

The coordinate is at (2, -1), when using a dilation with a scale factor of 3, multiply the coordinates by 3.

(2, -1) ------> (2 x 3, -1 x 3) ----------> (6, -3)

When reflecting the point over the y-axis, take the opposite of the x coordinate.

(6, -3) ------> (-6, -3)
