The ratio of the angle measures in a triangle is 5: 12: 19 . What is the measure of the largest angle?

Determine whether the lines are parallel, intersect, or coincide. 4x+2y=10, y=-2x+15

Determine whether the lines are parallel, intersect, or coincide. y=-3x+4, y=-3x+1

Determine whether the lines are parallel, intersect, or coincide. $6x - 12y = -24, 3y = 2x + 18$

Graph each line. $y+4=\frac{2}{3}(x-6)$

Graph the line. y = 3x - 4

Graph each line. y=-3x+4

Write the equation of the line. x-intercept 2 and y-intercept 4.

Write the equation of each line in the given form. The line through (4, 7) and (-2, 1) in slope-intercept form.

Write in point-slope from an equation of the line that passes through the point (4, 4) with slope 3.

Write the point-slop e form of the equation. of the line satisfying each of the conditions in Exercise. Then use the point-slope form of the equation. to write the slope-intercept form of the equation. Slope = 6, passing through (3, 1)
