Answer:
2x+1=y
Step-by-step explanation:
Parallel means has the same slope, so slope equals 2
2x+b=y (we don't know the y-intercept)
plug in x and y
2(-4)+b=-7
-8+b=-7
b=1
so, 2x+1=y

Answer:
? We don't see any graphs to choose from
Step-by-step explanation:
Graph a dotted line (to show it's not included) with y-intercept 1 and slope 1/2. Test the origin (0, 0) in the inequality:
This is true, so shade the side of the line that the origin is on (above the line).
Next inequality...
Graph a solid line with y=intercept 1 and slope 1. Test the origin.
True! Shade the side of the line the origin is on (below the line). See image2, attached.
Graph a dotted line with y-intercept -1 and slope -2. Test the origin (0, 0).
True, so shade the side the origin is on (above the line).
The solutions are located where all the shadings intersect. See image3. The solutions are above the red line, above the green line and below the blue line.
Answer:
y = 3/4x + 10
Step-by-step explanation:
The equation of a line is y = slope * x + y-intercept
To find the slope, you choose two points and do (y1-y2)/(x1-x2): Point 1 can be (4,13) and point 2 can be (8,16) so, slope = (13-16)/(4-8) = -3/-4 = 3/4
The y-intercept is the value of y when x is 0, so it would be 10.
Put it together and you get y = 3/4x + 10
