Use point-slope form to write the equation of the line in slope-intercept form that passes through the points (0, -5) and (-3, 4).
Slope formula: m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction
Point-slope form: y – y1 = m(x – x1)
Slope-intercept form: y = mx + b
Choose the equation of the line.
y = –3x – 13
y = –3x – 5
y = –3x + 5
y = Negative one-third x + 13
A line passing through the points (6, –2) and (–2, 4).
Complete the work shown:
1. Use slope formula to find the slope.
2. Substitute a point and slope in point-slope form.
3. Distribute the slope through the parentheses.
4. Solve for the y-variable.
1. m = StartFraction 4 minus (negative 2) Over negative 2 minus 6 EndFraction = StartFraction 6 Over negative 8 EndFraction = negative three-fourths. 2. y minus 4 = negative three-fourths (x minus (negative 2)). 3. y minus 4 = negative three-fourths x minus three-halves.
4. y = negative three-fourths x +
