Graphing linear functions
how do you determine the x intercept of a line given is eqaution?
set y = 0 and solve for x
what is the y intercept of the line y =-3x+4
y intercept is the point where the line crosses the y axis
y=-x+5
slope:-1
y intercept:5
The formula to find the slope (m) between two points (x1, y1) and (x2, y2).
What is (y2 - y1) / (x2 - x1)?
What is the slope of a horizontal line?
0
how do u graph a line using slope intercept form (y=mx + b)?
plot the y intercept (0,b) as your first point the use the slope (m) as rise over run to find a second point,starting from the first point the connect the two points with a line
set the equation of the line to 0 then solve for x
y=2x+3
slope: 2
y intercept:3
What is a function whose graph forms a straight line called?
linear function
What is the slope of a vertical line?
undenfied
what is the y intercept of the line represented by the equation y=-3x-1
The slope-intercept form of a linear equation is y=mx+b, where m is the slope and b is the y-intercept.
how can you find the y intercept of a line
determine the value of y when x is equal to 0
y=(1/2) x -4
slope 1/2
y intercept -4
What is the standard form of a linear equation?
Ax+By=C
Find the slope of (4,-2) and(-1,2)
What is -4/5
How would u graph a line using the point-slope form (y-y1=m(x-x1)?
Graph the line given the point and slope
what is x intercept
this is the point where the line crosses the x axis
y=- (2/5)x+10
slope -2/5
y intercept 10
Tell whether the function is linear and turn it into standard form of linear equation: y=x+3
Yes can be written as -x+y=3
Find the slope of (20,3000) and (60,2000)
What is -25
what is the y-intercept of the line represented by the equation y=2x+3
the y intercept of the line is 3
What is the x-coordinate of the point where the graph intersects the x axis called
What is the x intercept
car rental charges $25 per day plus $0.50 per mile. Write a linear equation to represent the total cost (c) as a function of miles driven (m).
0.50m+25
Tell whether the function is linear and graph the function
Yes it is linear.
Find the slope of the equation: 6x + 5y=30
What is 6/5
