Answer:
So, y = 2x + 7;
Then, 2x = 4( 2x + 7 ) - 16;
2x = 8x + 28 - 16;
2x = 8x + 12;
- 6x = 12;
x = - 2;
Then, y = 2· (-2) + 7;
y = - 4 + 7;
y = 3.

Answer:
The x intercept is (3/2,0)
The y intercept is (0,-3)
Step-by-step explanation:
Y+5=2(x+1)
To find the x intercept, set y =0 and solve for x
0+5=2(x+1)
Distribute
5 = 2x+2
Subtract 2 from each side
5-2 =2x +2-2
3 =2x
Divide by 2
3/2 =x
The x intercept is (3/2,0)
To find the y intercept, set x =0 and solve for y
y+5=2(0+1)
y+5 = 2*1
y+5=2
Subtract 5 from each side
y+5-5=2-5
y=-3
The y intercept is (0,-3)
If the question is to find the slope-intercept form of both lines, here's the answer:
Both lines pass through the point (-3,-4), so we can use these coordinates in both equations. The slope-intercept form is represented by y=mx+b, with m the slope, b the intersection of the line with Y'Y for x=0, y and x the coordinates of a point.
Let's first apply all these for the first line, with a slope of 4.
y = mx + b
y=-3; x=-4; m=4. All we need to do is find b.
-3 = 4(-4) + b
-3 = -16 + b
b=13
So the equation of the first line is y= 4x + 13.
Now, we'll do the same thing but for the second line:
y=-3; x=-4; m=-1/4, and we need to find b.
-3 = (-1/4)(-4) + b
-3 = 1 + b
b= -4
So the equation of the second line is y=(-1/4)x - 4
Hope this Helps! :)
Answer:
Choice #2
Step-by-step explanation:
Your linear function is in the slope-intercept form of a line, y = mx + b, where m is the value of the slope, and b is the value of the y-intercept. The number in the m position in your equation is 1/6, and thee number in the b position in your equation is 7. So the second choice is the one you want.
