Answer:

y = -2x + 9

Step-by-step explanation:

Using the slope intercept equation y=mx+b, we can see that the slope of the line parallel to y = -2x + 7 is -2.

m = -2

Use the point slope formula y - y1 = m(x - x1) to find the line that runs through (4,1)

y - 1 = -2(x - 4)

Simplify

y - 1 = -2x + 8

y = -2x + 9

You can check your answer by putting in the point and seeing if the equaiton is true

1 = -2(4) + 9

1 = -8 + 9

1 = 1

True

Please help!!!!!!!!!!!!!!!
VMariaS [17]

equation form: y = mx + b

where m is the slope, and b is the y-intercept.

slope = (y2 - y1) / (x2 - x1) = (13 -8) / (11 - 5) = 5/6

y = 5/8 x + b (replace x and y by 5 and 8)

=> 8 = 5/6 * 5 + b

=> 8 = 25/6 + b

=> b = 8 - 25/6 = 23/6

==> equation: y = 5/6 * x + 23/6

11+8q=3q-19 I need help please idk the answer
iren2701 [21]

Answer:

-6

Step-by-step explanation:

1) combine all like terms

(bring 3q to the left and 11 to the right so you can combine the like terms)

(doing that will make 3q negative and 11 negative since your moving them so their sign changes as well)

8q-3q=-19-11

5q=-30

Q=-6

Hope this helps
