Hi there! Hopefully this helps!

<h2>Answer: r = 7.</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2>

17 = r + 10

Swap sides so that all variable terms are on the left hand side.

r + 10 = 17

Subtract 10 from both sides.

r = 17 - 10

<h2>Subtract 10 from 17 to get, you guessed it, 7!</h2>

HELP ME WITH THIS MATH PLEASE!!
Anna007 [38]
A. slope is rise/run. can count up 3 right 2. slope = 3/2
also by slope formula m = (y - y1)/(x - x1)

B. y-intercept is the y coordinate where the line crosses the y-axis.
See that it is at y = -4 on the graph?
To use the slope.. go backwards from the closest point (4,2) down 2 left 3 gets you to the next point (2,-1) then go down 2 left 3 again to get to y-intercept (0, -4)

C. y = (3/2)x - 4

How you get it is by putting in the values into the standard equation for a line; y = mx + b
m is slope and b is y-intercept.

Please help asap…………
finlep [7]

Step-by-step explanation:

the most common form of line equation is

y = ax + b

a is the slope of the line. it is expressed as the ratio

y coordinate change / x coordinate change

when going from one point to the other.

b is the y-intercept (the y value when x = 0).

so, in our case, the slope is 2, the y-intercept is -3.

the y-intercept gives you the first point : (0, -3)

using the slope of 2 we know that for every unit x increases, y increases by 2.

so, you can pick a next point e.g. x = 2, which makes y = -3 + 2×2 = -3 + 4 = 1

that gives us (2, 1)

mark both points on the chart and then draw a straight line through both points.
