Answer:
y = 6x +1
Step-by-step explanation:
To write the slope-intercept form equation for a line, you need to know the slope and the y-intercept. These can be found from their respective formulas.
__
<h3>slope</h3>
The slope of a line between points (x1, y1) and (x2, y2) is given by the formula ...
m = (y2 -y1)/(x2 -x1)
For points (-1, -5) and (0, 1), the slope is ...
m = (1 -(-5))/(0 -(-1)) = 6/1
m = 6
<h3>y-intercept</h3>
The y-intercept is the value of y where the line crosses the y-axis. That axis is where x = 0. There is a formula that can be used to find the y-intercept from the slope and a point on the line:
b = y -mx . . . . . y-intercept of line with slope m through point (x, y)
However, one of the given points is already the y-intercept: (0, 1). It tells you b=1.
<h3>equation</h3>
The slope-intercept equation is ...
y = mx +b
y = 6x +1
Answer:
X = 4, x = -10
Step-by-step explanation:
Solve for x by finding a, b, and c.
Answer:
Sample Response: The y-values of equivalent ratios increase at the same rate as their x-values. The vertical distance between points is constant, and the horizontal distance between points is constant. This forms a straight line.
Step-by-step explanation:
Answer:
x=2.5
y= -7
Step-by-step explanation:
1.)make y the subject of any equation
4x-y=17
-y=17 -4x
y = -17 + 4x
2.)substitute it in the next equation
-2x + 3(-17 + 4x)= -26
-2x -51 + 12x = -26
-2x + 12x - 51= -26
10x -51= -26
10x = 25
x = 2.5
3.) substitute the x- value into any equation
4x -y = 17
4(2.5)- y = 17
10 - y =17
-y = 7
y = -7
The answer to this problem is x▶3
