Answer:

y = (1/2)x + 3

Step-by-step explanation:

The points are separated by 1 vertical unit for each 2 horizontal units, so the slope of the line through them is ...

slope = vertical change / horizontal change = 1/2

There is a point on the y-axis at y=3 where x=0, so we know the y-intercept of the line is 3. Then, in slope-intercept form, the equation of the line can be written ...

y = slope · x + y-intercept

y = (1/2)x + 3

1.4 solving two step and multiple-step equations 2r+20=200​
Over [174]

Answer:

r = 90

Step-by-step explanation:

Our goal is always to get the variable we're trying to solve for on one side of the =, and everything else on the other side. Since we are solving for r here, we want to get rid of the 20 first, and then the 2.

subtract 20 from both sides:

  • 2r = 200 - 20 = 180

divide both sides by 2:

  • r = 180 / 2 = 90

I need help with this!!!
sergiy2304 [10]

Answer:

D. y = -2x + 16

Step-by-step explanation:

The slope of a parallel line is the opposite reciprocal of the given slope so it'd be -2.

I think the formula is called point slope form? y-y1=m(x-x1).

y - 4 = -2 ( x- 6 )

y = -2x + 12 + 4

y = -2x + 16
