5x + 10 = -4x - 17
+4x +4x
5x + 4x = 9x
9x + 10 = -17
-10 -10
-27
9x = -27 9x/9 = -27/9
x = -3
Answer:
y = -3x
Step-by-step explanation:
Slope-intercept form:
Slope formula:
Given points: (-2, 6), (2, -6)
(2, -6) = (x1, y1)
(-2, 6) = (x2, y2)
To write the equation in y = mx + b form, we need to know the slope(m) and the y-intercept(b). To find the slope, input the two given points into the slope formula:
Simplify:
6 - (-6) = 6 + 6 = 12
-2 - 2 = -4
The slope of the equation is -3. To find b, we can input the value of the slope and one point (in this example I'll use (2, -6) into the equation:
-6 = -3(2) + b
-6 = -6 + b
0 = b
The y-intercept is 0. Now that we know the slope and y-intercept, we can write the equation:
y = mx + b
y = -3x + 0
y = -3x
The equation written in slope-intercept form is y = -3x.
Step-by-step explanation:
So you add one over the other
3x-2y=7
-3x+5y=5
=
3y=12
Then you divide 3 from both sides
(3y)/3=12/3
y=4
Then you substitute the y=4 in to the equation of your choice
3x-2(4)=7
3x-8=7
3x-8=7
+8 +8
3x=15
x=5
