How to graph an equation using slope and y intercept
Asked by admin @ in Mathematics viewed by 267 People
Use the graph to find the slope and y-intercept to write
the equation in slope-intercept form.The graph shown is y=x+
Answered by admin @
Answer:
Slope = -1/2
Y-intercept is y = -1
Equation of the line:
Step-by-step explanation:
The slope intercept form is y = mx + b
Where, m is slope, and
b is y-intercept
We need 2 points to find these. One point is (-2,0) and second point is (2,-2).
THe formula for slope, m, is m =
Plugging the points, we get the slope to be:
y-intercept is the point where the line crosses the y axis. Looking at the graph, y-intercept is y = -1.
Now we plug slope and y-intercept into the slope-intercept form to get:
