Writing Equations in Slope - Intercept Form - Using Desmos.
Slope - Intercept Form: y = mx +b

2
y = mx + b
Where m is the slope and b is the y-intercept.
Simply replace the values for m and b into the equation.

Multiple Choice
Write the equation of the line passes through the point (3,-1) and has a slope of 2.
y = 2x + 1
y = -1/3x
y = 2x - 7
y = -x + 3
8
Multiple Choice
Write the equation of the line passes through the point (2,1) and has a slope = 4.
y = 3x - 2
y = 4x - 7
y = 4x + 7
y = 3x + 3
9
Steps
Find the slope between the two points - replace this for m.
Use one of the two given points to find x and y
Solve for b.
Write the Equation.

Multiple Choice
In slope-intercept form, write the equation of the line passing through the points (-3,4) and (-4,2).
y = -2x + 10
y = -2x - 10
y = 2x - 10
y = 2x + 10
11
Multiple Choice
In slope-intercept form, write the equation of the line passing through the points (-4,1) and (-3,2).
y = -x + 5
y = x + 5
y = x - 5
y = -x + 5
12
Steps
