Question 214764: Find slope-intercept form of the equation of the line with the following intercepts:
x-intercept: -7
y-intercept: 5 Found 2 solutions by Earlsdon, drj:Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! The slope-intercept form is:
y = mx+b Now b, the y-intercept, is given as y = 5, so...
y = mx+5 The x-intercept is given as x = -7 and this occurs when y = 0, so...
0 = m(-7)+5
7m = 5
m = 5/7
The final equation is:
y = (5/7)x+5
Step 1. The slope-intercept form of the equation is given as y=mx+b where m is the slope and b is the y-intercept at point(0,5). For our example, b=5.
Step 2. To find the slope we use the x-intercept which means it occurs at point (-7,0) or x=-7 and y=0.
Step 3. Then
Add 7m to both sides of equation
Divide 7 to both sides of equation
Step 4. ANSWER: The equation of the line is }
I hope the above steps were helpful.
