This is about how to write linear equation in the form of y=mx+c

• 1
The World Of Linear Equations Writing Linear Equations In Slope-Intercept Form Y = mx + b
• 2
If you are given: The slope and y-intercept Finding the equation of the line in mx + b form. Given: slope and v-intercept. Just substitute the "m" with the slope value and the "b" with the y- intercept value. • Slope = % and y-intercept = -3 Y= mx + b
• 3
If you are given: A Graph Find the: y— intercept = b = the point where the line crosses the y axis. change in y s rise Slope = run change in xls y— intercept = b = -g up 1 Slope = over 2 Y= mx + b
• 4
If you are given: The slope and a point Slope point (4,-1) and a point (x,v). To write equations given the slope and a point using Point-Slope Form. Point-Slope Form -1 2 -1
• 5
If you are given: The slope and a point Given: slope (m) and a Slope and point (4,-1) point (x,v). Substitute x, y, and m into y = mx+b and find the value of b (the y-intercept). Then write the equation substituting m and b values into y = mx + b. Y = mx -1 -2 = 1/2(4) m = 1/2 2 -2 b So! and b

If you are given: Two points Finding the equation of Find the: rise the line in mx + b form. Given: Two points. First find the slope (m) and then substitute one of the points x and y values into y = mx+b along with the slope. Point (-2, -4) & Point (2, -2) Y= lhx change in y's Slope = run change in x's Slope and point (2, -2) Y = mx -2 = 1/2(2) -2 -3 m = 1/2 1 b So! and b = -3
